【摘要】：[目的]试图在保证区域各类用地合理配置、生态良性循环的基础上对宁国市土地资源承载力进行评价,以期为多层次、多指标的土地资源承载力研究提供一种可行的研究方法与思路。[方法]以安徽省宁国市为研究试点,从耕地、建设用地、生态用地等3个方面构建土地资源承载力评价指标体系,运用层次分析法确定指标权重,利用承载指数法建立宁国市土地资源承载力评价方法。[结果]揭示了宁国市土地资源承载现状为"可载"状态,符合宁国市实际情况。[结论]认为应将资源环境承载力评价与监测预警工作切实有效地融入政府管理工作当中,需进一步开展资源环境承载力动态监测与评估技术的研发,职能部门需统筹建立动态数据库,实现信息共享机制。
[Abstract]:[objective] to evaluate the carrying capacity of land resources in Ningguo city on the basis of reasonable allocation and ecological virtuous cycle of all kinds of land use in Ningguo city, in order to make it multi-level, The multi-index study on the carrying capacity of land resources provides a feasible research method and train of thought. [methods] taking Ningguo City, Anhui Province as a pilot study, from cultivated land to construction land, The evaluation index system of carrying capacity of land resources is constructed in three aspects of ecological land use, and the index weight is determined by AHP. The evaluation method of carrying capacity of land resources in Ningguo City is established by means of bearing index method. [results] it is revealed that the present situation of carrying capacity of land resources in Ningguo City is "loadable". In accordance with the actual situation of Ningguo city. [conclusion] it is considered that the evaluation and monitoring and early warning of the carrying capacity of resources and environment should be effectively integrated into the management of the government, and further research and development of the technology of dynamic monitoring and evaluation of the carrying capacity of resources and environment should be carried out. Functional departments need to establish a dynamic database as a whole, to achieve information sharing mechanism.
