绿地指标体系的建立及其评价,是反映绿地系统建设水平高低的科学依据,是城市生态绿地系统构建的前提与基础.本文从绿地规划定量指标、绿地结构定量指标、社会服务功能定量指标三个方面构建皖北地区县城绿地系统功能与结构评价指标体系进行全面量化计算与评价研究.结果表明:皖北地区县城绿地系统斑块类型齐全,绿化总量不足,破碎化程度大.附属绿地在城市绿地中占主导地位;皖北地区县城建成区绿地系统建设水平整体不高,其中蒙城、颍上、阜南、利辛、灵璧、固镇绿地建设水平较好,寿县、五河、濉溪、临泉、萧县、泗县、太和、怀远绿地建设水平一般,凤台、砀山、涡阳绿地建设水平较差.
The establishment and evaluation of greenland index system is a scientific basis for reflecting the level of greenland system construction and is the prerequisite and foundation for the construction of urban greenland system.In this paper, three quantitative indicators of greenland planning, quantitative indicators of green space structure and quantitative indicators of social service function The author made a comprehensive quantitative calculation and evaluation research on the system function and structure evaluation index system of county greenbelt in northern Anhui Province.The results showed that the patch type of greenbelt in county of northern Anhui was complete and the total amount of greening was insufficient and the degree of fragmentation was large.Acneral greenbelt in the city The construction of green space in the built-up area in northern part of Anhui Province is not high in overall level. The construction level of green areas in Mengcheng, Yingshang, Funan, Lixin, Lingbi and Guzhen is good, and Shouxian, Wuhe, Taixi, Linquan, Xiaoxian, Si County, Taihe, Huaiyuan green building level general, Fengtai, Dangshan, Guoyang green building level is poor.
