【Abstract】 On the basis of field survey and samples collected, the status of vegetation in Shahe reservoir was studied. The results show that revived forest and man-made forest are dominant beyond 50 meters of normal water level in Shahe reservoir. The plants are in abundance, comprised of 70 families and 253 species. Among them are Pteridophyte, which includes 7 families and 9 species, and Angosperm, which includes 63 families and 244 species. However, vegetation in some areas is severely destroyed due to human disturbances, resulting in the increasing scarcity of wild plants. Once vegetation protection web is destroyed, drinking water’s safety is threatened. Therefore, the local government should attach great importance to the vegetation protection.更多还原
