宁乡市耕地种植属性空间格局特征的三种量化方法
Three quantitative methods on spatial pattern characteristic of cultivated land planting attributes in Ningxiang City
摘要
Abstract
Taking Ningxiang City as an example,this study uses the results of the 2023 land change survey and employs spa-tial statistical methods,including nearest neighbor index,spatial kernel density estimation,and standard deviation ellipse methods,to quantitatively analyze the spatial pattern characteristics of cultivated land planting attributes.The results show that the planting attributes of cultivated land in Ningxiang City exhibit significant spatial agglomeration characteristics.The northwest Weishan area and the southeastern region form low-value cultivated land areas due to terrain constraints.The prin-cipal axes of four types of cultivated land are coupled with the topographic base elevation along the southwest-northeast direc-tion.Non-grain crop land shifts toward the northeast hilly areas,reflecting the relationship between planting types and topog-raphy.The uncultivated land appears fragmented and island-like in areas with high urbanization.Food crops are concentrated in the traditional grain-producing areas in the southwest,while non-food crops and food-non-food crop rotation are mainly distributed in the central plain areas.The analysis results provide a scientific basis for cultivated land protection and utiliza-tion in Ningxiang City and serve as an important reference for the formulation and implementation of future land management policies.关键词
