| During the "Ninth Five-Year Plan" to "Thirteenth Five-Year Plan" period,researchers devoted themselves to the control of rocky desertification in karst areas,with remarkable results.After the treatment of rocky desertification,a unique ecological derivative product has been formed.The 19 th National Congress of the Communist Party of China pointed out that it is necessary to thoroughly implement the construction of Xi Jinping’s ecological civilization.The “Opinions on Establishing and Improving the Value Realization Mechanism of Ecological Products”issued by the Central Committee of the Communist Party of China in 2021 pointed out that it is necessary to speed up the market-oriented operation of ecological products and build a sustainable path to realize the value of ecological products.South China Karst is the largest and most concentrated karst area in the world,and the vulnerability of its natural environment directly affects the vigorous development of the regional economy.In recent years,with the development of national rocky desertification control,the number of ecological derivatives of rocky desertification environmental control（referred to as rocky desertification ecological products）has become increasingly abundant,but most of them are still mainly agricultural products.Further developing ecological products for rocky desertification control,promoting agricultural ecological construction,and promoting the marketization of ecological products are the most effective means to consolidate the effectiveness of rocky desertification comprehensive governance and the achievement of poverty alleviation.It is also an effective way to promote the coordinated development of ecology,economy,and society in rocky desertification control,and is of great significance to ecological environmental protection and industrial income increase in karst areas.It integrates human-land system theory,agricultural ecology theory,food science theory,ecological economics theory,regional economic development theory,geographic marketing theory and other theories,aiming at scientific and technological problems such as the small market scope and short market time of ecological products in karst areas.In the Shibing Karst Mountain Canyon Non-potential Rocky Desertification Comprehensive Control Research Area（referred to as the Shibing Research Area）,which is a typical ecological industry development in the karst area,the large-scale Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ was selected as the research object.From 2020 to 2022,through spatial visualization,regression analysis and other analysis methods,the sales space pattern of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ and the basic theoretical research,sales space,application demonstration and other aspects of the promotion of market value will be analyzed.Focus on clarifying the relationship between the quality of ecological products and the market after rocky desertification control,explore the potential market for rocky desertification control ecological products,propose value-enhancing technologies suitable for the study area,and carry out application demonstration,verification,and promotion.It is expected to provide scientific and technological reference for consolidating the achievements of rocky desertification control and poverty alleviation.（1）It is found that the natural and geographical conditions in karst areas have high adaptability to planting Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,and the main influencing factors of environmental climate factors,soil environment and ecological product quality of irrigation water city are clarified.The natural environment is significantly related to the quality of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’: Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’are planted on slope to ladder,The quality generally presents the characteristics of middle slope > slope top > depression.The weight of 10 main quality indexes of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ was analyzed by analytic hierarchy process,and then the same indexes as those of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ with large market were determined.The fuzzy comprehensive evaluation showed that the soluble sugar under the bagging of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ in Shibing karst area was 13～16,the water content was 85%～90%,the titratable acid was < 0.1%,and the vitamin C content per 100 g was 1～1.95 mg,The content of stone cells per 100 g is 0.81～1.23,which is close to the level of organic pear in Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’planting demonstration base in Henan Yellow flood area.Appropriate natural conditions are the key to the quality assurance of agricultural products and the premise of market mining.Therefore,the organic unity of quality,market and environment should be emphasized.（2）The spatial pattern of supply and demand of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ is clarified,and the relationship between the quality of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’and sales space is clarified.The sales space is close to the place of origin,and the better the quality of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,the greater the sales space.The sales of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ are mainly concentrated abroad,and my country is the main exporter of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’.The main foreign markets include Japan and South Korea in East Asia,Malaysia,Thailand,and Singapore in Southeast Asia,and France,Germany,and the United States in Europe and the United States.While cities of different sizes in China have different demands on the quality of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,firstand second-tier cities have greater demand for fine fruit,higher requirements,and higher profits,while third tier and below are mainly bulk pears.Large and medium-sized cities in the north account for about 70%of the country,mainly in Henan,Shandong,Shaanxi,Anhui,Beijing,Hebei,Gansu and other provinces and regions,while in the south they are mainly in Sichuan,Yunnan,Hunan,and other provinces.Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ is an ecological derivative product of rocky desertification control in Guizhou in the past 10 years.The development of its industry and the effect of rocky desertification control are mutually reinforcing spiral processes.Ecological industry is the key to ecological restoration and long-term and stable poverty alleviation in karst areas.This study combines quality-market-environment to break the contradiction between economic development and environmental protection.The expansion of the ecological product market and the restoration and protection of the environment can complement each other.（3）The Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ quality grading system was proposed,and the Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ were divided into excellent,excellent,good,and average.The relevant census and regression analysis were carried out by using SPSS data processing system software,and the calculation model of soluble solids,total acid and solid acid ratio was obtained.Based on the quality calculation model,field investigation,combined with the real-time appearance quality of the Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,the grading system of the Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ was obtained.Different grades correspond to different packaging and markets,as well as different profits.For the first time,a grading system combining the internal and external quality indicators of the Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ was proposed to provide a more scientific evaluation and grading for the grading of the Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’.The more perfect the grading system,the more conducive to the expansion of sales space.Quality is the basis for market consolidation and expansion.At the same time,grading can promote the improvement of agricultural management technology,thereby promoting the benign development of agricultural production.（4）The key technologies of more effective storage,preservation,and deep processing for enhancing the value of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ were proposed and demonstrated.The application of air-conditioned cold storage extends the shelf life of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,staggers the market peak,and combines with the deep processing technology of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ winemaking processing,to increase the added value of ecological products and reduce product losses.According to the experimental comparison of the three methods of cold storage storage,1-MCP treatment storage and controlled atmosphere storage for Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,it is found that the storage method with the best storage effect is controlled atmosphere storage.Compared with the general cold storage refrigeration technology,the air-conditioned cold storage can prolong the storage period by about0.5 to 1 times.The fresh products stored in the air-conditioned cold storage can extend the fresh-keeping period to 21 ～ 28 days after leaving the warehouse,which is 3 to 4 times that of the general cold storage.Extending the shelf life of commodities and staggering the market peak will help reduce market saturation.The deep processing technology of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ wine is becoming more and more mature.The brewing ratio of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ and wine is 1:1,and its market value is 10 times that of fresh fruit of Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’,reducing the loss of fresh fruit by 1/5,bringing nearly500,000 yuan to enterprises and farmers.Therefore,the preservation technology and deep processing technology of mature ecological products are important means to enhance the value of ecological products.Extending the shelf life of commodities is conducive to reducing market saturation and further expanding the Pyruspyrifolia（Burm.f.）Nakai cv.‘Whangkeumbae’ market. |
