Vegetation restoration is the main aspect of soil and water conservation monitoring, and is the important indicator of ecological environment restoration. Vegetation area was extracted on the basis of image land use classification to efficiently and accurately calculate vegetation restoration rate, provide a reliable basis for soil and water conservation monitoring by using UAV aerial survey image data, unsupervised classification and visual discrimination method of ENVI. The result shows that: (1) UAV can quickly obtain high resolution images of the small areas with high visibility and stable wind conditions; (2) UAV orthophoto map can be used to classify land use status of water and soil conservation on the basis of unsupervised classification of Envi 5.1 software; (3) based on the analysis of objects in various regions, vegetation can be divided and vegetation area can be extracted in visual judgement criterion; (4) the horizontal precision of the orthophoto map of the test area obtained by using the UAV can reach 0.2 m resolution. High precision data obtained from UAV remote sensing can be used for land use classification and vegetation restoration analysis in small scale of soil and water conservation projects.
