The Strategy Research Of Ecological Network Planning In The Main Urban Area Of Harbin

With the level of the city raise and natural living environment fall, the earthecosystem became weak extremely. This phenomena is the challenge to thecontemporary city plan. City ecological network planning as the hot point for the cityplanning, landscape ecology and related professional researchers, which use it as theimportant tool to promote the city back to nature. Harbin is one of the biggest cities inChina which developed rapidly in northeast of china. The focus of Harbin is urbandevelopment without destroy the natural. Under this background, this paper takesHarbin city’s7areas as the research object and it applied landscape index and networkanalysis to obtain the strategies of ecological network planning.On the present situation of green patch, corridor, on the basis of statistical analysisand summary of two rounds of overall planning, articles on Harbin existing plaquenetwork, river network, road network was related to the index of landscape ecology andsummary of the three kinds of network problems. And it applied of α, β, γ index on cityecosystem. It lay a good foundation to optimization of ecological network in Harbin.Through the research, the article from macroscopical to microcosmic put forwardrelevant solutions by ecological network construction principles. This article argues thatit should become from the node and connection for Harbin ecological network.According to the plaque network, river network, network road, this paper put forward tostrategy. This article expounds the three types of ecological network integration in orderto achieve the best results. For patch and corridor, which are the elements for ecologicalnetwork, the article gives concrete improvement measures. So that it can beimplemented.This article from the city overall planning perspective, from qualitative analysis toquantitative analysis on ecological network analysis and Strategy Research of Harbinecological network. Research shows that in the city of construction of ecologicalnetwork is to promote the city ecological environment effective tool. Applicationmethod for analyzing landscape pattern and the network analysis method for cityecological network planning the planning process more structured, the planning schemebecome more reasonable.
