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、2000、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3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。According to the pressure-state-response conceptual model, ecological health evaluation indexsystem of Yangshuo County was established based on land use spatial pattern. Remote sensing data andinterpretation of land use of 1991, 2000 and 2009 were used, based on the pixel scale, land use spatial patternand indicators of these three periods were extracted by RS and GIS technology. Ecosystem health of the studyarea was calculated and space map was produced by the evaluation model, then the ecosystem health of thestudy area was assessed. The results showed that：（1） the overall ecosystem health of Yangshuo County was notgood, but gradually changed to a better state;（2） area of healthy ecosystem state（healthy and very healthy） waslocated in northeast and southwest of Yangshuo, area of general healthy ecosystem state（sub-healthy andunhealthy） was located in the middle of Yangshuo;（3） land use spatial pattern change in Putao, Baisha andYangshuo was the main reason of the general ecosystem state.
