基于耕地质量评价的县域基本农田分区研究

摘要

耕地综合质量评价与分区是基本农田划定和高标准基本农田建设的前提与基础。从土壤质地、农田基础设施、耕地空间形态及规模3方面选取10个指标，以综合指数模型及GIS分区技术，将绥化市北林区耕地划分为优先划定、适宜调入、重点建设和退出型耕地类型区。优先划定型耕地综合质量最优，是高标准基本农田建设的重点，是粮食生产和现代农业建设的示范优选区域；适宜调入型耕地也可作为基本农田近期建设的优先区域；重点建设型耕地宜采取中、远期土地综合整治规划分步建设；退出型耕地不宜划定基本农田。研究成果可为区域基本农田分区及高标准基本农田建设提供依据。%Quality evaluation and partitions of cultivated land are the premise and foundation for the basic farmland demarcated and high standard basic farmland construction. 10 indicators were selected to construct the evaluation index system from soil quality, infrastructure construction, spatial form and size. With the help of the GIS data processing and spatial analysis function, using the comprehensive index model, cultivated land can be divided into priority delimit, suitable, the key constructive and exit types of cultivated land in Beilin district of Suihua City. Due to comprehensive quality optima of the priority type farmland, it's the focus of the construction of high standard basic farmland object and food production and the construction of modern agriculture demonstration optimization area. Suitable to arable cultivated land also can be used as a priority area of the recent construction of basic farmland. Key constructive cultivated land should be taken to long-term land comprehensive improvement plan to build. Type out of cultivated land should not be defined as basic farmland. Research results provided the basis for basic farmland zoning and high standard basic farmland construction.
