Study On Greenland Landscape Pattern In Chenzhou City

Urban green is an important environment factor on urban sustainable development, scientific green land planning can leads city develops more healthy and sustainable. Under the guidance of landscape ecology theory, the research will be more scientific in green land planning and construction.In this paper, under the guidance of landscape ecology theory, through a combination of qualitative and quantitative research methods, using GIS software Arcgis and pattern analysis software Fragstats, and then through vector analysis of Chenzhou City in the green status, drew the pattern index; Through the analysis of the pattern index, spread out the evaluation to the green landscape pattern of Chenzhou City;:1. The conclusions of the pattern index analysis:Generally speaking, uneven distribution of green patch in Chenzhou City, a small number of types of green patch in the area of distribution advantage, and of the overall diversity is in a low level. Judging from the size of plaque, the total number of small patches (≤0.2hm2) is 937, which in the dominant position of all the plaque types, and there are 71.86% accounting for the total number of landscape patches; View from the plaque type, settlements and subsidiary unit green patch with the largest number of patch,there are 654 plaques, and accounted for 41.79% in the total number of landscape patches. Peri-urban green is the largest share of the type in the 6 green types, the area is 306.3899 hm2, accounted for 50.64% in the total area of plaque.2. The evaluation findings of Landscape pattern:in this paper,5 indexes are collected as evaluation indexes of Landscape pattern through Delphi method. Comparison from a variety of green types, the best of the comprehensive evaluation of the landscape is Scenic woodland; Peri-urban green space,green subsidiary units and settlements green space is in a good situation, Park green space,Peri-urban green space and green space of rood are in the middle, Square and green street are the worst.And on the evaluation results, propose the optimize green space landscape pattern measures to Chenzhou City:1.Summary and then proposed the "Three Galleries, Five Belts, One ring, Multi-point" structure of the form of green space, protecting the future development of urban green space.2. It proposed suggestions on the green space construction, which including four suggestions which is park green area to expand, uniform allocation of green patches, strengthen the green corridor building, green space diversity to improve.In this paper, the use of GIS technology on the status of Chenzhou City for patterns of green, is the first study in green related research of this city; Completed a lot of green space system planning work in the early stage of investigation and research, which provided a more detailed data in the future Green Space System Planning of Chenzhou City. The evaluations and planning in urban green in Chenzhou, also provides the feasible suggestions and reference value on how can urban green develop sustainable.
