Study On Urban Parkland Layout Of Changzhou

The purpose of the study is to promote scientific and rational park layout for Changzhou. At present,Changzhou parkland development is in full swing,however,whether the distribution is acceptable to meet the demand of residents is the real problem.The article mainly aimed at existing problem of Changzhou parkland to point out scientific and rational proposal.This research studied the park green structure and efficient service area of Changzhou parkland ,the conclusions as followed:1.By GIS technology,related parkland data was obtained.Based on the knowledge of land- scape planning and use of landscape ecology as well as the basic theory,a quantitative calculation of green information was checked out.Through a series of landscape diversity,landscape domi- nance index,the minimum distance index,landscape connectivity and so on,structural defects were summaried.The results showed that major parks was in the leading position in Changzhou, parks pattern was in more broken state and unfavorable for ecological, leisure,refuge, etc.2.By buffer analysis,the service radius was calculated.The study of park service radius was aimed to examine services for people.The author used GIS buffer analysis theory to draw the radius of Changzhou,services parks as the research objects.The results showed that parks could not meet the use of the surrounding people.The service radius need to be further strengthened.3.Based on the structure and layout of the park green space problems,combined with results of field research,the end of the paper pointed out several optimizational proposals to the future construction of park layout.
