【摘要】 以TM影像为数据源,以重庆南川市为研究区,结合地面调查数据,利用ERDAS遥感处理软件,对植被覆盖度信息提取方法及植被覆盖度与植被指数的关系进行了研究。运用统计分析方法,分析得出研究区植被覆盖度与归一化差异植被指数(NDVI)之间具有显著的相关性,研究结果可为利用遥感资料进行大面积植被覆盖度估算提供了理论依据。更多还原

【Abstract】 In this paper,the authors study the method of gaining the percentage vegetation cover information,the correlation between percentage of vegetation cover and normalized difference vegetation index(NDVI) in the south of Chongqing city,by TM data integrated with the field surveying data,and remote sensing interpretation software-ERDAS IMAGINE.The correlation between percentage of vegetation cover and normalized difference vegetation index(NDVI) is analyzed by statistical method,the results show that there have obvious correlation,and the correlation coefficient is 0.948.The research provides the basic for calculating the percentage of vegetation cover in large area by interpreting TM image.更多还原
