Evaluation Of Cultivated-Land Quality In A Land Consolidation Area Of Fujin City

The security of cultivated land resources has an important impact on national food security.Scientific,accurate and comprehensive understanding of the quality of cultivated land resources is the core and key to the management of cultivated land resources.As a strategic deployment at the national level,land improvement is a useful practice to protect cultivated land resources and guarantee food security.Therefore,the evaluation of cultivated land quality in the land improvement area is conducive to the timely investigation of the cultivated land quality status after the land improvement,the monitoring of the land improvement effect and the promotion of high-standard farmland construction,which is conducive to the promotion of the comprehensive protection of the "trinity" of cultivated land quantity,quality and ecology,so as to achieve the goal of ensuring national food security.From the farmland productivity,space geography,ecological environment and construction four aspects to define the connotation of cultivated land quality,with patches as evaluation unit,comprehensive utilization of weighted composite index model and the disorder degree model,discusses Fujin City renovation,the renovation of three typical sample area of area and land reclamation area of cultivated land quality characteristics and differences,identify different regional cultivated land quality obstacle factor,for Fujin City land utilization,protection and promotion to provide theoretical reference.The main conclusions are as follows:(1)the cultivated land quality in the research area is generally good,and the cultivated land quality is sorted as reclamation area >.Regulation area & gt;Non-remediation area.In terms of land quality,the overall level of the study area is mainly good and equal,and the land quality ranking is regulation area = non-regulation area >Reclamation areas,mainly due to the geographical location of reclamation areas congenital conditions;In terms of project quality,the overall level of the research area is medium,and the project quality is reclamation area >.Regulation area & gt;The non-remediation area indicates that there is still a certain gap between the remediation area and the reclamation area in terms of capital investment and construction level.In terms of space quality,the overall level of the research area is good and equal,and the order of space quality is reclamation area >.Non-remediation zone >The regulation area is mainly affected by the slope of the terrain,indicating that the land leveling in the regulation area still needs to be strengthened.In terms of ecological environment quality,the overall level of the research area is mainly good,and the ecological environment quality is ranked as non-regulated area.China & gt;The regulation area is mainly affected by the geographical location.Therefore,at a certain ecological environment level,the improvement project has an obvious effect on the improvement of cultivated land quality,but compared with the reclamation area,the cultivated land quality in the improvement area still has some room for improvement,and the improvement strength still needs to be strengthened.At the same time,it is necessary to adhere to the scientific cultivation of fertilizer and steadily improve the level of cultivated land capacity.(2)for regions with different levels of regulation,the order of obstacle degree in the criterion layer has spatial quality >Engineering quality >Land quality >The law of ecological environment quality.The index obstacle degree of the whole research area is slope >Farmland forest network rate >Trench density >Field regularity >Road access,through different regional barriers of the top five indicators mainly includes slope farmland Lin Wanghua rate,ditches,density,field neat degrees,road access,and organic matter,six indexes including three indicators within the engineering quality criterion layer,two indicators within the space quality guidelines,one index within the soil fertility quality criterion layer,further confirm the diagnosis of the criterion layer obstacle factor,slope degree is larger space is the cause of the disorder degree is greater than the project quality.So this article is based on storing grain in the land "and" agricultural modernization "with the development of demand,around the disorder degree of the three largest criterion layer and six indicators,and from the ongoing renovation project construction,the promotion of new agricultural management main body and scientific fertilizer combined with planting and raising three aspects suggest improve cultivated land quality measures to provide theoretical reference for Fujin City land utilization and ascend.This study is helpful to find out the advantages and disadvantages of cultivated land quality after land improvement.It is of great significance to monitor the cultivated land quality level,strengthen the improvement of cultivated land quality in different regions at medium and low levels,establish a long-term mechanism for cultivated land protection,promote the improvement of cultivated land production capacity,and guarantee the national food security.
