泰州市基本农田空间配置探讨

泰州是江苏苏中地区重要农业生产基地。随着经济发展，基本农田存在被大量挤占风险。需要对现有耕地进行科学评价，从保障粮食生产安全的角度，将最适宜耕作的耕地保护下来，禁止非农占用。利用需求模型测算泰州基本农田需求量为32.7×104 hm2，按照基本农田的保护率为85%计算，2020年泰州市基本农田适度保有量在26×104 ～30×104 hm2。通过1 km×1 km的格网，选取生产能力和发展压力两类指标，综合评价耕地适应性，按照高适宜等级优先分配的原则，将基本农田分配到空间地域单元，达到空间优化配置目的，为土地管理决策提供依据。结果表明，到2020年，泰州市基本农田将主要配置在兴化市，占60%以上，泰州城区随着工业化进程加快，基本农田被占用风险加大，保有量比较低，占全市的比重不到3%。〖

SPATIAL DISTRIBUTION OF BASIC AGRICULTURAL LAND IN TAIZHOU CITY

As one of the important agricultural production bases in Jiangsu Province,the economy of Taizhou develops very quickly,meanwhile the basic agricultural land is in danger of being occupied.From the viewpoint of food security in Jiangsu, a number of agricultural lands should be kept in Taizhou on the bases of scientific analyses of present cultivated land.In this paper,it was estimated that the need of basic agricultural land was about 327×104 hm2.According to the ratio of 85% as protection level, about 26×104~30×104 hm2 cultivated land should be regarded as suitable agricultural land.Using grid of 1 km×1 km, we selected two basic levels standing for production ability and developmental pressure to evaluate the suitability of cultivated land in Taizhou. According to the priority of suitability, we can distribute cultivated land into different grids and optimize the spatial distribution of agricultural land.The result shows that most of suitable cultivated land will be distributed in Xinghua in 2020,and the ratio is over 60 percent,while in the buildup area of Taizhou,the ratio is quite low,no more than 3 percent,with the process of industrialization.
