摘要:

以绍兴古城及周边地区为研究区域,利用居住建筑的空间分布来测算评价区域内常住人口空间分布;继而利用GIS工具来测量公园绿地服务范围,并统计出市民可享用公园绿地的选择机会的空间分布情况,从而在精细尺度上基于空间公平视角实现对公园绿地的可达性测量。研究表明,公园绿地服务范围内部存在着不公平现象,进而提出了相应的公园绿地布局优化策略。

Abstract:

As a kind of urban public facilities, parks are the main places for citizens’ amusement and relaxation. Only when citizens can conveniently access to parks, they can function well. Park accessibility is considered as the main factor that will influence citizens’ use of them. That is the reason why scholars have paid attention to studies on the accessibility to parks for recent decades. In the previous studies on the evaluation of accessibility to parks, the relevant measures mainly focused on the ratio of parks’ service area to the total area, while spatial distribution variation in citizens selection opportunities for parks use was somehow overlooked, which, to some extent, embodied relevant studies’ limitations in representation of spatial equity on parks’ spatial distribution. From the perspective of opportunities equity, reasonable park spatial distribution lies in: citizens possess the same selection chance for parks use when they pay the same cost to visit them. On the other hand, the relevant studies always ignored population distribution, or simply assumed that population was evenly distributed, which will finally influenced the evaluation results of accessibility to greens. Taking the ancient city and its neighbor region in Shaoxing City as the study area, residential building information were utilized to estimate the distribution of permanent resident population, then GIS network analysis tools were used to measure the service area of parks, the distribution of selection opportunities residents possessed for parks use was revealed, and park accessibility was obtained in the fine spatial scale from the perspective of spatial equity. The analysis results revealed that opportunities inequity exists in the service area of parks, which can be more accurately measured by incorporating the attraction index. Some relevant optimization strategies for park distribution were proposed such as improvement on spatial quality of parks, increase of community parks inside the ancient city, parks construction synchronized with urban development, reduction of spatial inequity by utilizing the price mechanism in parks’ densely distributed area. However in this study, attraction index was quite objective, and the capacity of park was neglected as well. Unique demands of specifically group such as the elder, kids or the disabled for parks were unfortunately not considered, which will somehow deviate the origin that public resources should be leant to the disadvantaged group. The further study should be conducted in the near future.

Key words: parks, opportunity equity, accessibility
