摘要
运用GIS和RS技术,提取了郑州市区绿地信息,采用定性分析与定量分析相结合的方法,分析了绿地景观构成、景观格局、建设现状,结果发现,郑州市绿地结构不合理,空间分布不均衡,绿地破碎化程度较高,绿地廊道景观未形成网络。针对这些问题,提出相应的措施和建议:优化绿地结构,强化生态功能,强调城市绿地结构的整体性和系统性;改变建筑优先的用地规划模式,建立"开敞空间优先"的规划原则,避免绿地破碎。
Zhengzhou greenbelt information is obtained with GIS and RS technology based on the qualitative and quantities analysis. The greenbelt structure, landscape pattern, and building status are analyzed. Results show the greenbelt structure is irrationality in Zhengzhou. The spatial distribution is unbalanced ; the greenbelt is extremely shattered, and greenbelt corridor doesn ＇ t form the network. Some measures and suggestions are proposed such as optimizing the greenbelt structure, strengthening ecological function, emphasizing the integrity and systematicness of urban greenbelt structure, changing the land usage planning mode of building precedence, and setting up the open room precedence principle to avoid greenbelt shatter.
