其结果表明：林木覆盖率与绿度值呈正相关；

The results showed, The forest cover percent was positive correlation with greenness indices;

根据干物质累积速度与绿度值的关系求出最佳气候条件下的最大绿度值作为标准绿度值。

Then, based on the relationship between the rate of greenness and the rate of accumulated dry matter, the maximum greenness was derived as the standard greenness.

遥感数据再处理以及合理划分试验同步区是提高作物面积（产量）与绿度值回归模型信度的重要途径。

Dividing duplicated areas reasonably and re processing the remote sensing data are important ways for improving credit limit of regression model between winter wheat area (or yield) and Green Value.
