本项研究工作直接应用“国家资源环境遥感宏观调查与动态研究”项目和“中国资源环境数据库”取得的最新数据和资料,研究并提出了土地利用程度综合指数计算方法和指标体系,在此基础上,全面分析了影响中国土地利用程度变化的自然环境因素和社会因素,分析了中国土地利用程度的区域分异规律,提出了中国土地利用程度的“极地”模式,并建立了中国土地利用程度的经度、高程模型。

This paper presents an index system and a method for calculating the comprehensive index of land use degree. The latest data from two projects titled “Remote Sensing Macro Investigation and Dynamic Study of National Resources and Environment” and “Resources and Environment Database of China”have been fully applied. In addition, this paper analyzes the regularity of the regional differentiation of land use degree in China and the socioeconomic and physical factors which affect the change of land use degree in China.The“polar” model and the “Longitude Distance” model of land use degree of China are also developed.
