Analysis on Vegetation Succession Model and Process under Groundwater Exploitation in Subei Lake Watershed
摘要
Abstract
[ Objective] The study aimed to analyze vegetation succession process under groundwater mining.conditions in Subei Lake watershed. [Method] A succession model for vegetation and groundwater level was constructed through field survey,and was used to predict the vegetation' succession rules and process according to the changes of groundwater level in Subei Lake watershed under groundwater exploitation. [ Result] fii Subei Lake watershed,aquatic vegetation was most closely related to groundwater level,followed by mesophytic vegetation,while peammophiloufr and xerophytic vegetation did not have obvious relation with groundwater level. When groundwater level wa?small,dominant plants grew well,but they grew worse or died. As the groundwater level fell constantly .vegetation succession would occur gradually from aquatic vegetation to mesophyt-ic and xerophytic vegetation,from Carex L. And Iris ensata Thunb shoary land to Achnathemm splendent siioafy lands,from Salix psammophila shrubs to Artemisia desterorum Spreng and Caragana korshinskii shrubs,and from Populus simotni to Salix macsndana. [Conclusion] The research could provide scientific references for studying the relationship between groundwater resources and ecological environment in Subei Lake basin.关键词
