开发区作为中国工业化和城市化快速推进的主要增长极和载体,承受着城市经济和城市建设带来的巨大环境压力。结合长春高新技术产业开发区绿地建设现状,指出绿地数量少且分布不均,城市建设大量挤占绿化用地,绿地布局结构和网络体系不够完善,绿地建设特色不突出是开发区绿地系统存在的问题。在此基础上,确定了到2020年开发区绿地率为45%,人均绿地面积为35.97m2,人均公共绿地面积为29.24 m2等绿地规划总体控制指标;提出了点、线、面相结合的"一环、两带、流绿、线网、多园"的环网式的绿地系统空间模式;从基质、廊道、斑块等景观生态要素规划了不同尺度绿地系统建设思路。
Development area endures big environmental press which comes from urban economy and urban construction as mostly increase pole and carrier of Chinese industrialization and urbanlization advancement. Considering the green land construction status quo, the article indicates that urban construction impropriates green grass land and green land distribute unbalanced, and that green land layout and network are not perfect and characteristic of green land construction do not stand out in development area. Based on this, we set green land rate as 45%, green land area as 35.97m2 per capita, public green land area as 29.24m2 per capita, and green land commanding index of general plan before 2020. We bring green land system space mode of "one ring, two strip, flowing green, line net and gardens" which unites dot, line and side of plan. From landscape ecology factors such as base, corridor, block and so on, we plan green land system construction train of thoughts in different measure.
