Habitat Characteristics Analysis In Landscape Planning And Design About Riparian Zone Of Sichuan And Chongqing

Riparian Zone is between the land and the river, locating on the both sides of the junction, which extends along the river bank until the area that the impact of the river disappears. Riparian Zone is closely with human life.There are a lot of functions, such as protection, buffer, link and resources.It has many types, because Chongqing and Sichuan are located in southwest of China,so there are many mountains and hills on both sides of the river.So the riparian zone of Chongqing and Sichuan is valley-type.In recent years, landscape planning project is watched everywhere.In order to understand the ecological environment of valley-type riparian zone and the influence of ecological environment clearly, the article expands the research from the three angles:1.When different riparian width vegetation types and their combinations, the contrast about the ability to intercept surface runoff.2. From the angle of the drainage, it states the influence of flood level and terrain, which use the region of HeChuan. And in order to ensure the notice when landscape planning, the article uses the ecological environment compare which come form three kinds of different districts.3.Take beaches at Binjiang road of Suining Hedong district for example, the article studies specific vegetation combination gradient when carry out landscape planning for small scale riparian zone beaches.The results of investigation and research indicated:1.There are four types of vegetation which locate in riparian zone of Chongqing and Sichuan, they are farmland, shrubs, arbor and grass.There are eight combinations of different vegetation types:the plantation and farmland, the arbor and farmland, the shrub, grass and farmland, the arbor, shrub and farmland, the arbor and shrub, the shrub and grass, the arbor,shrub and grass, the arbor and grass.Among them, the arbor and the shrubs have the better ability to intercept surface runoff; three vegetation combination have the better ability to intercept surface runoff, they are the arbor, shrub and grass, the arbor and grass, the arbor and shrub.The bigger width of vegetation, the stronger ability to intercept surface runoff.When the width of vegetation is more than 30 meters, the growth rate decreases about the ability to intercept surface.2. Because of the influence about flood level,terrain and altitude, small wetlands which locate in the both sides of riverway are connected to the shape of beads. They behave the ecological features alone which whether there are flood control dam or not, mainstream and tributary of river, or different application types of land.3.Because of the influence of manual excavation,terrain and altitude, the water form Fujing are drawde into the wetland, forming plenty of small wetland patches, forming its disposition gradient of plant.This thesis provides some suggestion for the ecological planning:l.Use the tall vegetation planting material to soften the hard landscape of levees.2. The choice of materials with plant must have the abilities to resist water flooding, dry, poor and soil erosion, we must pay attention to the safety of plant references.3. When in landscape planning, we not only consider the landscape effect, but also the ecological benefit, making the riparian zone planning of ecological keep healthy and beautful.
