Abstract:: According to the disasters detailed survey achievements of 12 counties and 1 district in Yan’an area, counting and analyzing the survey data, combining with remote sensing technology, the correlation between eco-environment(vegetation coverage rate, land-use types) and geological disasters were summarized as follows. The higher rate of vegetation coverage is, the smaller development degree of geological disasters is, otherwise, the higher development degree of geological disasters is. In the aspect of vegetation coverage types, the woodland coverage rate is the predominant influence factor for geological disaster density, and the grassland coverage rate has no distinct relevance with it. The land-use types that are related to human activities (cultivated land, water and water consevancy facilities land, urban and industry land, transportation constructiong land) are generally proportion to the geological disaster density. These results have the reference values for geological disaster prevention and reduction and land-use planning in Yan’an area.
