摘要: 依据压力-状态-响应概念模型,建立了基于土地利用空间格局的阳朔县生态健康评价指标体系。以1991年、2000年、2009年的遥感数据和解译的土地利用数据为基础,基于像元尺度,采用RS和GIS技术,提取阳朔县三个时期的土地利用空间格局和指标信息,借助评价模型对研究区生态系统健康进行计算并制作空间分布图,然后对研究区生态系统健康进行时空动态评价。研究结果表明:(1)阳朔县整体生态系统健康状态一般,但正逐渐向生态系统健康较好状态转变;(2)阳朔县生态系统健康较好状态(健康和很健康)的区域主要位于阳朔东北部和西南部的山区和丘陵,阳朔县生态系统健康一般状态(亚健康和不健康)的区域主要位于阳朔的中部;(3)土地利用空间格局的转变是葡萄、白沙、阳朔等乡镇生态系统健康呈一般状态的主要原因。

Abstract: According to the pressure - state - response to the conceptual model, based on land use spatial pattern of Yangshuo County, established ecological health of the evaluation index system. Remote sensing data and interpretation of land use based on data from1991 to 2009, based on the pixel scale, using RS and GIS technology, extracted Yangshuo three land use spatial pattern and indicators. With the evaluation of model calculation and production of space maps of ecosystem health in the study area, then evaluated the spatial and temporal dynamic of ecosystem health in the study area. The results show that: (1)The overall ecosystem health of Yangshuo County is not good, but gradually change to be a better state of ecosystem health; (2) Ecosystem health status (health and very health) area is located in northeast and southwest of Yangshuo; Ecosystem health of the general state (sub-healthy and unhealthy) area is located in the middle of Yangshuo; (3) Land use spatial pattern changed in Putao, Baisha, Yangshuo township health was the main reason of the general ecosystem state.
