摘要: 城市化是经济快速发展的必然结果和要求。以苏锡常为代表的快速城市化苏南板块正在导致原有的城乡景观发生快速的变化(优化与恶化并存)。基于城市景观生态调控方法,通过城市景观生态规划(整体共生的理念)、城市景观生态工程(循环再生的理念)和城市景观生态管理(竞争自生的理念),提出快速城市化过程中城市景观生态优化调控的构想。以苏南地区的常州市武进区为例,从其地理环境背景及景观演化出发,提出可持续发展的景观生态优化的基本原则和目标。将城镇整合成以中心城区斑块为核心的向外辐射的4个城镇景观生态发展斑块,即5大斑块平衡组团的景观格局,协调各行政区域的城市化、工业化发展;典型景观生态片区建设以淹城保护区斑块为核心,以氵鬲湖太湖斑块和绿色空间基底景观生态建设为主体,依托“二纵三横”的生态廊道网络,形成整个武进富有韵律的生态网架,从区域整体上改善、优化城乡景观生态,有效避免景观破碎与退化和生态环境恶化。

Abstract: Urbanization is the target and consequence of rapid economic development of China in the early 21st century.By now,the rapid urbanization in southern Jiangsu Province has induced both positive and negative changes in urbanrural landscapes.Based on the existing ecological cybernetics methods,and applying the concepts of landscape ecological planning,landscape ecological engineering,and landscape ecological management,this paper built a conceptual framework for the landscape ecological control in the Wujin District of Changzhou City,a representative of southern Jiangsu Province,aimed to avoid the negative changes and to ecologically optimize its urbanrural landscapes.The landscape ecological control here addressed the issues of landscape patterns,landscape ecological processes,and interactions between human activities and landscapes,while the strategy consisted of an intensive and extensive understanding of regional geographical and ecological settings,some principles and targets of landscape ecological control,five patches landscape in balance,and typical landscape ecological areas construction,including Yancheng Site Protection Area,Gehu Lake patch and Taihu Lake patch,urban green space matrix,and highway corridor network.
