Western China is vast, expansive, sparsely populated, and economically underdeveloped, but it plays an important role in economic and social development in China. While the west is a crucial base of power resources, it is also rich in fauna and flora resources and the major habitat for China's many rare wildlife species. Therefore, protecting its ecological environment is vitally significant not only to the west itself, but also to social and economic development of the whole country. However, because of the fragility of the ecological environment of the west, plus improper human activities in the long past, the ecological environment of western China has been seriously damaged. This article describes the following 10 issues regarding damages to western China's ecological environment: (1) Crisis of Water Resources; (2) River Dry-Up; (3) Lake Shrinkage; (4) Retreating Glacier and Rising Snowline; (5) Aggravation of Marsh Closure for Farming and Damages Caused Thereby; (6) Serious River and Lake Pollution and Deteriorating Water Quality; (7) Degradation of Ecological Function of Forests; (8) Degradation of Grassland; (9) Land Desertification; and (10) Drastic Reduction in the Number of Wildlife Animals and Plants, and Threat of Extinction for Certain Species. The author offers several suggestions to address these issues.
