摘　　要：基于赤水桫椤保护区保护成效的需求,本研究应用遥感解译技术对贵州赤水桫椤国家级自然保护区1993年至2015年之间的生态系统保护成效进行分析研究。本项研究首先建立保护成效评价指标体系,选用地表覆被、植被指数和水体指数指标表征生态系统变化。研究采用1993年和2015年的Landsat数据,对其进行分类解译处理,分析保护区地表覆被、归一化植被指数(NDVI)、归一化水体指数(NDWI)变化情况,分析保护区的生态系统保护成效。研究结果表明,研究区近几年地表覆被变化总体呈现良性态势,农田裸地转换为森林的面积逐步增加,保护区西部植被覆盖率与水体指数明显增强,保护区的保护成效整体显著。Based on the demand for the protection effectiveness,this study applied remote sensing interpretation technology to analyze the effect of ecosystem protection in Chishui Alsophila National Nature Reserve from 1993 to 2015.In this study,the protection effectiveness evaluation index system was first established,and the land cover,vegetation index and water body index were used to characterize the ecosystem changes.The study used Landsat data from 1993 and 2015 to analyze the changes of land cover,normalized vegetation index(NDVI)and normalized water body index(NDWI)in protected areas,and reveal the ecological status of protected areas and system protection effectiveness.The results showed that the change of land cover was in a positive direction in recent years,and the area of farmland converted to forest has gradually increased.The vegetation coverage and water body index in the western part of the protected area have been significantly enhanced,and the protection effect of the protected area is overall remarkable.
