摘要：

土地利用现状评价是土地利用总体规划的基础和出发点，为了正确的认识土地利用现状，编制好土地利用总体规划，以重庆市黔江区为例，应用权的最小平方法建立土地利用现状评价体系和标准，从土地开发利用程度、土地集约利用程度、土地利用综合效益3个方面对土地利用现状进行定量评价。结果表明，黔江区的土地利用综合评价分值为70.58，处于基本合理利用阶段，建议在未来土地使用中以社会主义市场经济建设为取向，内涵式集约型利用土地资源，提高土地综合利用效益，实现土地资源的可持续利用。同时，为土地利用现状评价提供了新的方法。

Abstract:

The status of land use evaluation is the base and starting point of general land use planning, in order to correct understanding current situation of land utilization, to prepare the general land use planning, this paper takes Qianjiang District, Chongqing City as an example, applying weighted least-square method to establish the land utilization status evaluation standards and system. This system evaluates quantitatively three aspects of land utilization status: land exploration and utilization degree, land intense use level and comprehensive benefit of land use. Results show that the Qianjiang land use comprehensive evaluation scored 70.58, indicating the area is in a basically reasonable use phase. The advice of improving the land comprehensive utilization efficiency and achieving the sustainable utilization of land resources in socialist market economy construction as an orientation is given. A connotative intensive utilization of land resources in land use in future is also proposed. At the same time, this paper provides a new method for land use status evaluation, bearing a practical significance.
