Study On State And Optimization Of Spatial Configuration Models Of Rural Greening In Shandong Province

The difference between urban and rural systems in China makes the development speed and quality of rural areas lag far behind that of cities.For the sake of better development and higher welfare benefits,rural talents choose to devote themselves to the development of big cities,resulting in serious loss of rural population and even hollowing out in some areas.In the successful implementation of the rural revitalization strategy,we must prevent the excessive loss of rural population.The important guiding principles for the implementation of the rural vitalization strategy include giving priority to the development of agriculture and rural areas,strengthening the institutional supply of rural vitalization,and persisting in the integrated development of urban and rural areas.The construction of the new countryside will certainly bring about great changes to the greening and beautification of the countryside,which puts forward higher requirements for the construction of livable countryside.If the rural greening construction can be guided by benign laws and regulations and standardized application of science and technology in this process,and lead the rural greening construction onto the road of scientific standardization,China's vast countryside will be of great benefit.According to the dominant economic development model,the villages selected in this survey are divided into agricultural industry villages,forestry industry villages,industrialized villages and tertiary industry villages.This paper analyzes the characteristics and modes of greening in different industries and studies the greening schemes.The main results of this study are as follows:(1)there are obvious differences in the greening structure of villages with different industrial structures.From the perspective of the composition types of tree species,the dominant tree species in forestry industry villages are mainly economic tree species.The dominant tree species in agricultural villages are ornamental tree species.The dominant tree species in the industrialized villages are mainly economic tree species and ornamental tree species,while thedominant tree species in the tertiary industry villages are mainly ecological production tree species.(2)the green space composition structure of different industrial structures cannot help but be the same,among which the greening form of road space is mainly the green belt of road trees.The green space of parking lot only appears frequently in industrialized villages and tertiary tourism villages.The four types of villages in the composition of public activity space all contain public activity squares,but the small gardens appear more frequently in industrialized villages and tertiary industry villages.The occurrence frequency of around-village-forest in forestry industry villages reached 100%,that of around-village-forest in tertiary industry villages reached 66.67%,and that of agricultural industry villages and industrialized villages was only 29.41% and 33.33% respectively.The frequency of green space in the water protection zone is related to the water source in the village.Except for the agricultural industry villages,the application frequency of green space has reached more than 50%.(3)in the current construction of village green space,the construction of road green space accounts for the majority of the villagers in the agricultural and forestry industry villages who are not satisfied with it,and the majority of the villagers who are basically satisfied with it in the construction of industrialized and tertiary industry villages;The construction of green space for public activities accounted for the majority of the villagers in the forestry industry and industrialized villages,the majority of the villagers in the agricultural industry villages held a basically satisfied attitude,and the majority of the villagers in the tertiary industry villages held a very satisfied attitude.In the construction of green space between houses,the majority of villagers in the villages of forestry industry,agriculture industry and tertiary industry are basically satisfied,and the majority of villagers in the industrialized villages are very satisfied.The villagers are not satisfied with the greening space in the village,which is concentrated in the late management and maintenance of tree species in the road greening space in the village.Green space for public activities in the village is lacking and facilities are obsolete.Villagers' demand for public green space tends to provide space for communication and activity environment,and their choice of tree species tends to be ornamental and of high economic value.(4)score different industrial types of rural greening modes in Shandong province.The total score of rural greening modes in Shandong province is above the passing grade and below the good grade.The score is from high to low: tertiary industry,industrialized village,forestry industry village,agricultural industry village.The richness factor scores of scenic spots and historic sites in four villages with different industry types were allpoor.(5)from the overall situation of the greening space at the present stage,the villages have insufficient understanding of the management and maintenance of the greening space at the later stage,resulting in a variety of conditions such as poor plant growth and lack of construction,and poor maintenance of pavement and public activity greening space paving.(6)of different industries rural overall optimization direction,for now the agricultural industry,forestry industry and the development direction of the village of industrialization has two,one is enlarging the scale of industrial development,to large-scale production of industry,the second is to build diversified economy type,while conducting major industry,the development of the third industry.Put forward the optimization plan for the village green space.
