Study On Ecological Environment Evolution And Adaptation Strategies Of Northeast Typical Wetlands

Wetlands are the most productive natural ecosystems and the most important survival of mankind's environmental, Because of more and more affect of the human activities, wetlands received a serious threat. Wetlands of northeast are the largest area in our country, and also are affected mostly by human activities. Protecting and constructing ecological environment and achieving sustainable development are a basic principle in the modernization of our country. Study on ecological environment evolution and adaptation strategies of northeast typical wetlands for protecting ecological environment and using Scientifically are very important.This issue through a joint inspection, observation, remote sensing interpretation and data collection, basicly grasp the northeast wetlands typical essence conditions, analyze distribution and evolution of the northeast wetlands by the way of landscape fragmentation, obtain panjin wetlands, zhalong wetlands, xianghai wetlands'changes of wetlands distribution and dynamic, landscape pattern, water areas, vegetation and climate-driven. At the same time, innovative consider the characteristics of the wetland, according to Meteorological Department, established combinating microcosmic with macrocosmic, and point with aspect, the business route of combinating the remote sensing, ground verification with monitoring points; Screening set up a wetland ecosystem monitoring indicators system; Initial established the methods of landscape fragmentation and wetland ecosystems.According to the dates analysis, it reveals the environment degradation trend of the Northeast typical wetland, and obtains the cause of effect the environmental change, at the same time, it advance the adapt counter measure for the environment degradation situation of the Northeast typical wetlands:reasonable delineating the range of protection and function regional; controlling rigidly spring and fall burning; strengthening reasonable deployment water resources; develop reasonably and pay attention to protect wetlands of the weather, above can offer data and scientific basis for national decision-making.
