摘要

The eco-environmental effects brought about by LUCC determine the supply of products and services in the region, and especially have an important impact on human well-being and the quality of the ecological environment. This article takes Zoige County as the research area to analyze and discuss the ecological environment quality of Zoige County. The results show that the ecological environment index of Zoige County in 2000, 2010 and 2019 were 0.541, 0.553, and 0.549 respectively. In the past two decades, the ecological environment index of Zoige County has been increasing first and then decreasing. The ecological environment of all townships in Zoige County There are obvious differences in the index, and the lowest ecological environment index in the entire study interval is Hongxing Town. The degree of interference in the territory by various external factors has deepened, and it has continued to deteriorate in some areas. The restoration and renewable ability of the ecological environment has been weakened to a certain extent. The quality of the ecological environment is generally in a relatively good state, and the regional ecological environment is maintained within a certain range. Dynamically stable.
