郑州市西北象限边缘区绿地景观构成梯度分析

Analyses of gradient changes of landscape composition for northwest quadrant transect of Zhengzhou City

以郑州市边缘区西北象限样带为研究区域,分成5个梯度,通过分析不同梯度绿地景观的构成,探讨绿地景观在城市空间扩展状态下的分布规律.结果显示,各类绿地景观在5个梯度的分布极不均匀,边缘区绿地景观构成以菜地、耕地为主,园林绿地较为缺乏,直接制约着区域环境质量的改善和游憩质量的提高.据此提出协调城市发展和绿地建设两者关系的有效途径,并提供不同梯度区绿地景观规划的辩护对策.

Taking northwest quadrant transect of Zhengzhou as an example,through analyses of its green space landscape heterogeneity gradient,this paper explored the distribution of green landscape in urban spatial expansion.Results showed that the distribution of green space landscape in five gradient is extremely uneven,and the fringe area mainly constituted in vegetable plots,cultivated land,while gardens and greenbelts relatively lack,which directly influences the regional environment quality and recreational quality.Effective ways were effered to coordinate the relationship between urban development and greenbelts construction,and the countermeasures to green landscape planning of different gradient were also provided.
