The paper used TM and MODIS data to acquire ecosystem types and quality condition parameters. The process involved the following steps: 1) TM images were used to classify the land use/land cover of Huzhou; 2) A method was developed to decompose MODIS NDVI pixels (500 m×500 m) into the same resolution scale of classified TM image, and the observed weather data were combined to compute the NPP (Net primary productivity) of different ecosystems; 3) According to NPP and statistical data, ecological capital of d...
