Abstract

Urban green spaces play an important role in urban ecosystems, they provide diverse environmental and social services to improve the quality of life in cities. In this study, based on the high resolution remote sensing images and other auxiliary data, we conducted a suitability analysis for the city of Changzhou under the support of Geographic Information System (GIS) technology. In addition, landscape index were also involved in the quantitative assessment of green landscape with high suitability. Results revealed that the green patches in Changzhou were seriously fragmented, middle and small patches accounted for 96% of the total amount of green patches and 40% of the total green landscape area. In the highly suitable region, the green patches with middle and small size should take up 45% of the total amount and 14% of the total area, its patch structure is obviously superior to whole the city. The Yellow Mountain, Qing Ming and Fang Mao Mountain area, in the northern and eastern part of Changzhou, were less fragmented. It is evidenced by a high aggregation index and a developed green landscape in these areas. For the low suitable areas, attention should be paid to increase the arbor coverage rate, reduce the fragmentation degree and the layout of patch.

基于土地适宜性分析的城市绿地景观评价

城市绿地在城市生态系统中发挥着重要作用，为改善城市生活质量提供了多种环境和社会服务。本研究基于高分辨率遥感影像和其他辅助数据，在地理信息系统(GIS)技术支持下对常州市进行了适宜性分析。此外，景观指数也参与了高适宜性绿色景观的定量评价。结果表明:常州市绿地斑块破碎化严重，中小型斑块占绿地斑块总数的96%，占绿地景观总面积的40%;在高适宜区，中小型绿地斑块数量占总量的45%，占总面积的14%，其斑块结构明显优于全市。常州北部和东部的黄山、清明和房茂山地区破碎程度较低。这些地区的聚集指数高，绿色景观发达。对于低适宜区，应注意增加乔木覆盖率，减少破碎化程度和斑块的布局。
