山区耕地利用变化的空间评价方法研究——基于RS和GIS系统

耕地利用变化评价研究具有重要的应用价值.为此,在对比了目前各种土地利用变化评价方法的基础上,提出了一种基于RS和GIS的山丘地区耕地利用变化的空间评价方法;同时,在分析反映耕地利用情况的主要因素的基础上,提出了一个耕地利用时空变化评价模型;最后,将上述山区耕地利用变化的空间评价方法应用于韶关市山区耕地利用变化情况的研究,获得了较好的应用效果.

A Spatial Assessment Method for Land Sustainable Use Based on RS and GIS

Assessment of the change of farmland use is of great important. After comparing the different ways of the assessment of farmland use change, a spatial assessment of the change of mountain range farmland use based on RS and GIS technology was presented. After the analysis to the primary factors reflects the farmland use, a spatiotemporal change model of had been put forward to assess the farmland use change. A comprehensive factor for sustainable development model (CISD) is made to reflect the region development situation. Finally, based on the mountain range farmland use change spatial assessment method mentioned above,the change of mountain range farmland use of Shaoguan city in Guangdong province (China)was studied, and a good effect was obtained. Such application proves the validity and feasibility of the spatial assessment method of the change of mountain range farmland use mentioned in this paper.
