Sanjiang Plain Wetland Aquatic Ecosystem Health Indicators System Research

Wetlands are important ecosystems on earth, In addition to the forests and oceans. The world’s three major ecosystems in the world. Wetland ecosystems play a vital role in protecting the global climate and ecological environment. Regulating climate, siltation epeirogenic cleaning up the environment, conserving water, homogenizing the floods, recharge ground water source, protected species of genes that control soil erosion. Rational use of resources and the protection of biodiversity and ecosystem diversity aspects play an extremely important role. In addition, the wetland also contains extremely rich animal plant and microbial resources. Makes the wetland ecosystem on Earth, living environment and ecosystem. Precisely because of the important role and status of wetlands have mentioned above, It was affectionately known as "the human gene pool" and "Cradle of Humankind"Sanjiang Plain, also known as Sanjiang lowlands,refers to the northeast of the northeast plains, is China’s largest swamp distribution zone. The Sanjiang Plain is located at latitude45°01’-48°27’56",longitude130°13’-135°05’26". Located in China’s northeast corner, the West put that in the southern end of the Xiaoxing’anling, Eastern part of the Ussuri River, northern originated in the Heilongjiang River, southern arrived Xingkaihu, The total area of51,300square kilometers. In the Sanjiang region, water resources are quite rich. Totaled18.764billion cubic meters. In the Sanjiang region, The per capita arable land area is roughly equivalent to five times the national average, Distribution of over250hectares of coniferous broad-leaved mixed forest in the hilly areas. Sanjiang Plain, the surrounding climatic conditions and ecological environment have played an important role in the regulation of, Therefore, it has important ecological, environmental, and economic value.Established on the basis of the evaluation indicators and evaluation methods of ecology and environmental science research, Investigation and analysis of the indicators within the ecosystem of Sanjiang Plain wetlands, Develop a more reasonable and relatively comprehensive wetland ecosystem health evaluation. Filter and principal component analysis and correlation analysis of their health, evaluation of candidate indicators, Thus to evaluate the health status of the wetlands in Sanjiang. At the same time, this article also pointed out that the health status of the wetlands of the Sanjiang Plain, Sanjiang Plain Wetlands are facing problems and proposed solutions of the response, also stressed the significance of the Sanjiang Plain in ecology. The study provide a theoretical basis and practical basis for the development of a reasonable wetland health assessment policy, Managers of protected areas to provide the scientific basis of management, Played an important practical significance and role of the further development of the protected areas.
