摘要

在界定土地利用系统健康内涵的基础上

构建了基于"压力-状态-响应"(PSR)模型的评价指标体系

采用熵值法和灰色预测模型

对中国土地利用系统健康状态进行了评价。研究结果表明:(1) 1999-2008年中国土地利用系统健康水平总体不断提高

综合指数从0.3935增加到0.5331

健康等级经历了"不健康-临界"状态的演变过程; (2)土地利用系统健康的压力指数总体上呈现下降趋势

状态指数和响应指数呈现上升趋势; (3)固定资产投资年增长率、人均耕地面积、土地垦殖率、水土流失程度、地均GDP等是土地利用系统健康等级提升的关键因素; (4) 2009-2015年中国土地利用系统健康水平呈现稳步上升趋势

2014年土地利用系统健康等级达到"亚健康"。并提出了提高土地利用系统健康水平的一些具体措施。

Abstract

On the basis of defining the meaning of the health of land use system

the evaluation index system for the health of land use system was constructed based on the press-state-response(PSR) model

then an empirical analysis was conducted in China by entropy method and grey prediction model. The results showed that: (1) The health level of land use system had been gradually improved from 1999 to 2008 in China

with the comprehensive index increasing from 0.3935 to 0.5331. The health of land use system generally experienced two stages

i.e.

unhealthy and critical state. (2) The pressure index showed a downward trend

while status index and response index showed a rising trend. (3) The growth rate of fixed asset investment

per capita cultivated land

land reclamation rate

extent of soil erosion and per capita GDP were proved to be key constraints for further improvement of the health of land use system. (4) The health level of land use system show a steady upward trend from 2009 to 2015

and the health degree of land use system reaches the sub-health state in 2014. Finally

some measures was proposed for the further improvement of the health of land use system.
