摘要
This paper analyzes the habitat features of different wetland vegetations in Yellow River Delta, identifies water and salt conditions of vegetation succession and explores the rules of vegetation succession. Based on the model LEDESS, integrates a great number of expert knowledge of relevant subjects, such as ecology, plant physiology, geography, hydraulic and agrology, couples the hydraulic model and underground water model, quantificationally simulates vegetation succession series under different ecological water supplement situations, shows the results with visual and spatial expression. Analysis LEDESS model simulation results: (I) After ecological water supplement, vegetation succession positive development, barren land, alkaline land, tidal flat decreases, while area of wetland marsh, ordinary meadow, and shrub increases. (2) Indicator species habitat suitability area increases, bird habitat quality improved significantly. Using LEDESS model to simulate vegetation succession under the situation of ecological water, to the image - makers to " see " the vegetation succession tendency and ecological effect after carrying out ecological water supplement measures, and provide the technical support for the ecological water supplement, wetland protection and rehabilitation in Yellow River Delta wetland.
