基于空间异质性的农业型县域耕地质量分区保护研究
Research on zonal protection of cultivated land quality in agricultural counties based on spatial heterogeneity
摘要
Abstract
Cultivated land is the material basis for human survival and development,and the evaluation of cultivated land quality is the key to cultivated land protection and management.According to the natural factors,location conditions and spatial quality of cultivated land,the evaluation index system of cultivated land quality was determined,and the cultivated land quality in Taigu District was comprehensively evaluated.The evaluation unit was carried out by village.The spatial heterogeneity of cultivated land quality was analyzed by using the spatial autocorrelation method,and the influence of the strategic zoning of Shanxi agricultural valley was considered.The cultivated land protection type area was divided on this basis.The results showed that the comprehensive evaluation score of cultivated land quality in Taigu District ranged from 51.63 to 91.50,and the proportion of cultivated land quality in general level or above reached 78.2%,which was at a high level as a whole,and the spatial distribution showed the characteristics of high in the northwest and low in the southeast.From the perspective of global spatial autocorrelation analysis,the global Moran's I value was 0.459 422,the P-value was 0,which was significantly lower than the significant level,and the Z-value was 9.787 706,reaching the 99.5%confidence level.Locally,the spatial autocorrelation type was positively correlated and clustered together,forming the so-called"grouping"phenomenon,while the negative correlation type was scattered within the region and the number of administrative villages was small.Based on the results of comprehensive evaluation of cultivated land quality and the spatial agglomeration characteristics of cultivated land quality,the cultivated land in Taigu District was divided into four types of areas:core protection area,quality improvement and yield increase area,characteristic agricultural area and industrial integration area on the basis of Shanxi agricultural valley strategic zoning,and corresponding protection measures were proposed according to the characteristics of each region.Scientific and reasonable evaluation of cultivated land quality in agricultural counties and the analysis of its spatial differentiation law should be carried out,and the differentiated management of cultivated land protection areas should be demarcated,which is very important to protect the quality of cultivated land within the county level,to ensure people's food security and the development of rural agriculture.关键词
