基于RS和GIS的福建省耕地、林地分布情况及其利用效益的分析

利用RS和GIS技术,将经济统计数据与基础地理空间数据、遥感影像数据相结合,对福建省耕地和林地的分布情况和利用效益进行分析.结果表明:福建省人均耕地面积仅为0.0464ha,低于全国人均耕地面积0.1001ha;林地直接效益(10.2万元 km2)与耕地效益(274.5万元 km2)比较相差较大;在运用"3S"技术对全省土地资源进行宏观监测与分析时,把经济统计数据引入到土地覆被 利用的统计数据中进行相关分析可以更好地体现人类经济活动与土地的人地效应,但在方法、技术上还有待进一步的研究和提高.

Covering and benefit analysis of arable land and forest in Fujian based on RS & GIS technologies

Using the technologies of RS and GIS, this paper focuses on the analysis and assessment of coverings and economic benefits of arable land and forest in Fujian province, where data from economic statistics, basic geographic data and remote sensing image are integrated. The results show that the average area of arable land per person in Fujian is 0.0464ha, which is less than the average of China ((0.1001)ha). The financial benefit of forest (102 thousand Yuan /km~2) is less than that of arable land (2745 thousand Yuan /km~2). It is shown that better results can be obtained by integrating the economic statistics with land use/land cover data in the study of the relationship between human activities and the land, while "3S" can provide technologies for macro-scale supervision and analysis of land resources.
