The Research On Landscape Ecology Planning In The City Wetlands Landscape

At the beginning of last century 70's, as a result of the rapid population growth and the one-sidedness in humanity understanding to the wetland, the wetland was destructed badly and used unreasonably. And it also cause to the area of wetland wither suddenly, the natural characteristic loses unceasingly, the ecology value drops unceasingly. The existence of natural wetland is faced with the serious challenge. Therefore, human should have paid much more attention on protecting the wetland. City wetland is not only as the quantity effective supplement , but also alleviate the threat and environment pressure in natural wetland. So it is the wetland care powerful measure. Because of its geographical position and environment, the city wetland is disturbed quite seriously by human. How to maintains the characteristic of city wetland and to satisfy the psychological demand of city people in the wetland landscape, has become our research topic.This research take the Zhuzhou lotus pond park as the example, and according to the wetlands landscape planning theory at home and abroad for practicing and researching. It also based on the theory of landscape ecology, planning, urban ecology, landscape designing and so on, and utilization the ViweGis and Fragstats system software as the support method to make the quantification analysis landscape stability, biodiversity, landscape space pattern and ecology corridor circuity in the lotus pond park wetland landscape. At the same time, we summarized the landscape process such as landscape corridor width and landscape minute belt, in order to maintain the base original landscape pattern and the species stability. The research results indicated as follows:(1) Through analyzing the constitution of Zhuzhou lotus pond park wetland landscape region ecosystem, from the inorganic environment to organism's constitution, as well as the zoology and botany survival environment analysis indicated that, the wetland ecosystem in the region is in condition. But there are some environment questions such as human excessively disturbance, agricultural chemicals pollution, partial wetlands resources artificial destruction excessively is still seriously. We should construct the wetland landscape area, to further repair the wetland ecosystem and protect the primary wetland.(2) We can know that through the the whole landscape pattern analysis of Hetang Park,the area of marsh is the biggest in the 8 landscape factors in Hetang Park,the absolute area is 35 hm~2,comparative area is 23.79% is 23.79%. Secondly is forest(33.4hm~2 22.71%), reed belt (27hm~2 18.35%) and shallow seas and tidelands (23.7hm~2 16.11%) . It shows that it has nice base to do the landscape ecology planning, the wetland landscape area in Hetang park is 100.2hm~2,occupying 68.1% of the whole park. According to broad sense difining of wetland, the wetland landscape area in Hetang park is 105.1hm~2,occupying 71.4% of the whole park. Therefore,Hetang park is very suitable to be built to a wetland park, we must well use these landscape factors when doing landscape ecology planning in Hetang park, connected these to be a park that has abundant function, adding biology diversity of the park, reform better entironment of the park.(3) According to the different of human disturbance intensity, we could divides the lotus pond park into three different landscapes belts to carry on the landscape pattern analysis. The conclusions are following:...
