Study On Ecological Planning And Biology Diversity Of National Reserved Wetland District Of Hongze

Wetland, which provides us with resources of water, biology, energy, transportation and traveling, is one of the most significant ecosystems on the earth. Its physic, chemic and biologic constituents interact, enabled wetland to have giant environmental functions and ecological benefits in many aspects that cannot be substituted for by others ecosystems, such as adjusting climate, self-controlling water source, storing floodwater for use in the future, avoiding drought, purifying water quality, protecting biodiversity. Therefore wetland together with forest and sea is called the most three biggest ecosystems on the earth. So it is main protect object of our human beings.The research of biology diversity is the premise of the protects and reasonable exploitation on wetland. As a tour way for win both protection and development, ecoplanning being subjected to worship extensively at home and abroad. A good eco-planning is one of the important prior condition deciding ecotourism can or not carry out its dual function for protect and develop. The biology diversity is one of the most important tour resources in wetland, its protect and reasonable exploitation is the most important thing in the wetland ecotourism planning.This text commences from research of biology diversity in the wetland, its research works include the following aspects:First, the diversity of plant and bird in wetland was studied in a systemic way. at the foundation that biology, diversity inquirer, that how to combine the biology diversity inquirer with ecoplanning resources assessment and the environmental protection planning together, make the use of resources and protect more scientific.Second, through the analysis on the ingredients of Hongze Lake wetland ecosystem, specially the plants' habitat distributions, it is demonstrated that the ecosystem is generally good, but there are some environmental troubles, such as excess innings, illogical manners of life and production, extensive management, the destruction from partial foreign species, and wetland reduction in cultivated region. Hence, the wetland construction can restore the ecosystem and conserve the wetland reserve.Third, water pollution is the main factor that affects the ecosystem of wetland. Through the analysis on the ingredients of Hongze Lake, the pollution of BOD is the first problem. Pollution of N,P is the other affection that we should pay more attentionsFourth, the paper innovates the approach of ecological planning, Idea planning mostly discusses objects, principles, stakeholders and ecological service values of wetland park construction. The objects are mufti-objectives of resource, education, industry, recreation and development, and the final goal is built up a national ecological model region. The principles are non-pollution and environment precedence, sustainable development, and ecological culture.Fifth, eco-planning of project and product and design are very important to heighten the quality of wetland. Ecosystem resources assessment and' environmental protection planning should be enhance as soon as possible. This paper based on Hongze Lake wetland, through resources investigation and analysis, promote some new concept and way, Inconsequence from theory and practice, some configuration concerning planning are promoted.
