摘要:土地资源可持续利用是社会经济可持续发展的物质基础和前提条件,其核心是在保持和改善生态环境的条件下,保证土地资源持续满足人类社会发展的需求。本文以高县为例,通过建立县域土地可持续利用评价模型,以分析县域土地资源持续利用现状,完成对县域土地可持续利用实现程度的定量评价,并分析和评价该县土地可持续利用的水平和阶段,从而发现其在土地可持续利用中存在的问题,探索促进土地资源可持续发展的有效对策措施,为土地部门宏观决策提供依据,达到促进土地资源可持续利用水平的提高。本文立足高县土地利用的现状,依据土地可持续发展理论,采用实证研究和规范研究相结合,定性研究与定量研究相结合,在充分占有和分析材料的基础上,采用德尔菲法(Delphi)构建高县土地资源可持续利用评价指标体系,使用层次分析法确定权重,通过综合权重计算方法,对高县从2002年到2007年土地可持续利用情况进行评价研究。研究结果表明:近几年,高县土地资源利用处于基本可持续阶段,对高县土地资源可持续利用影响较大的指标是:“复种指数”、“化肥施用强度”、“耕地有效灌溉率”等,为此提出高县土地资源可持续利用的对策。

关键词:土地资源评价指标体系可持续利用评价高县

Abstract: Sustainable utilization of land resources, the core of which is to grantee that the land resources can meet the demand of human society development, is the material base and precondition of sustainable development of society and economy.Taking Gao County for example, through building up an evaluation model of land resource sustainable utilization in Gao County to analyze the current situation of land resource utilization, then to quantitatively ae the accomplished level of land resource sustainable utilization, and to analyze and ae the level and stage of land resource sustainable utilization of Gao County, thus this paper finds the existing problems in land resource sustainable utilization, explores the effective measures to promote sustainable utilization of land resources, provides foundation for macrodecision-making of agency in charge of land to raise the sustainable utilization level of land recourses.

Based on the current situation of land utilization in Gao County and according to sustainable development theory, by combing empirical research with normative research, integrating quantitative and qualitative analysis, this paper aees the sustainable utilization of land resources of Gao County from the year of 2002 to 2007 by integrating weighing calculation methods.In this aement proce, aement indicator system of land resource sustainable utilization in Gao County is built up by adopting Delphi, and weighting is fixed by using analytic hierarchy proce on the basis of enough information material.

This research result shows that the sustainable utilization of land resources of Gao County has been in the basic stage of sustainable development in the recent years and the indicants that largely affect the sustainable utilization are as follows: multiple-cropping index, fertilizer using intensity, arable land effective duty of water and so on.Thus this paper provides strategy for sustainable development of land

resources in Gao County.

Key words: land recourses; aement indicator system; Suitability aement; Gao County
