The Analysis Of Green Landscape Pattern And Evaluation Of The Small Town In Yinzhou District Based On GIS

This paper select three typical small town Qiuai town, Xianxiang town, Zhangshui in YinzhouDistrict, Ningbo, according to the characteristics of small towns green space is divided into farmland,parks green space, road green space, production green land, protection green land,living green, theunit attached green, the other green, focusing the analysis on spatial patterns of the green landscape ofthe three small towns, were evaluated on the basis of the spatial pattern of the green landscape of smalltowns, designed for small towns green space ecologylandscape construction offer some suggestions.The main findings are as follows:1.Analysis of three small towns in Greenland mainly from the four indicators of the park green areaper capita, per capita green area, the ratio of green space and green coverage analysis, the resultsshowed three small urban green coverage rate of more than30%,per capitagreen area greater than80m2the xianxiang town green the highest rate of71.61%, Zhangshui green coverage of up to64.20%, whileper capita park area Qiuai the town up to1.22m2/person, but three small townsthe number of park areaper capita park area are far failed to meet the needs of local residents. The combination of these fourindicators, which Xianxiang town the most balanced, Zhangshui followed, Qiuai town last.2.The green patch number statistics, the total number of green patch in Qiuai Town9700,the totalnumber of green patch2968in Xianxiang town, the total number of green patch1475in Zhangshui.Overall, the Qiuai town green landscape fragmentation in the highest degree of green, Zhangshui degreeof fragmentation minimum.3.The analysis results show that the level of patch type and landscape level index greater than0.2hectares of green space in the three small towns in the proportion of plaque area were Qiuai town82.02%, Xianxiang town was97.95%, Zhangshui99.40%. It can be seen, these three small towns andmedium-sized green patch in the dominant position within the scope of the entire town of Victoria.Three small towns in the landscape fragmentation index Qiuai Town0.99, Xianxiang Town,0.91,Zhangshui0.87. Three small towns of the landscape pattern of the performance characteristics offragmentation, low connectivity, and small towns green show a different degree of uneven spatialdistribution. 4.This paper use a combination of subjective and objective weighting method, a comprehensiveevaluation of the expert score+Entropy Method to conduct a comprehensive evaluation of three smalltowns green landscape structure, the composite index of the order of the town of Xianxiang>Zhangshui> Qiuai town, this results with the small town of green level of consistent and comprehensiveevaluation of the expert score+entropy Method can objectively reflect the green status of the threesmall towns.
