我国森林植被的覆盖程度受到土壤、气候、海拔、人为等各种因素的互相影响，为了能够遵循“适地适树”原则而更加精确在不同地区栽种适宜的树种从而提高我国森林覆被率，利用遥感技术对全国森林植被及其所生长的条件进行调查是重中之重。本文以全国范围为研究区域，利用MODIS数据对土壤、植被及气候数据进行提取，引入梯形网格，对全国进行等经纬度的网格划分，利用ArcGIS，ENVI等软件绘出我国土壤类型、N、P元素及有机质含量、年降雨量、年最高温度及最低温度的温度等值线，再利用数据挖掘技术提取与森林植被覆盖率相关的影响因子得出我国现阶段森林植被覆盖图，计算出我国现有林地面积并对影响森林植被覆盖的因子进行数据库的录入。

Extent of forest vegetation cover by soil, climate, altitude, and other man-made factors which are influence each other, in order to followed the "suitable tree" principle more precise planted in different areas of suitable species to improve our forest cover rate, our study using the remote sensing technology for national forest vegetation and its growth is the most important to investigate the conditions. In this paper, nationwide as the study are, the use of MODIS data on soil , vegetation and climate data were extracted into trapezoidal mesh, such as longitude and latitude of the country for meshing using ArcGIS, ENVI software such plots of soil type, N, P elements and organic matter content, annual rainfall , maximum temperature and minimum temperature of the temperature contours , reuse data mining techniques to extract forest vegetation cover associated with the impact factor of the present stage of forest vegetation cover drawn maps, calculate China's current forest area and make the database entry.
