| Abstract: | In order to promote the sustainable utilization of farmland in Guizhou,based on the statistical data,using the indexes of average annual net primary productivity,annual amount,annual variation coefficient and average annual variation coefficient of net primary productivity,the quality of farmland ecosystem in Guizhou in 2000- 2010 was evaluated. And the space- time pattern of ecosystem of the farmland in Guizhou based on NPP and its influencing factors were studied. |
