摘要:

基于景观生态学的“格局-过程”理论,对维护江苏沿海地区地形地貌、水源涵养、生物多样性、游憩景观等生态系统服务的单一安全格局进行构建;根据“最小-最大约束”准则,通过镶嵌运算进行叠加,构建综合生态安全格局。运用MCR模型,设置并比对“生态安全模式”“经济发展模式”和“生态与经济协调模式”等不同模式对城镇空间扩展的影响,识别需严格保护的低安全水平区和未来城镇空间重点开发的高安全水平区。研究得出:“生态保护与经济发展”协调型模式更好平衡“生态-社会-经济”效益,合理确定城镇建设和产业发展空间,是城镇健康有序发展的最优模式。

关键词: 景观生态安全格局, 城镇空间, 扩展模式, 江苏沿海地区

Abstract:

The importance of ecological security space has attracted more and more attention in the top-level design of urban spatial expansion in China. That’s very necessary to identify security issues and key ecological factors from regional scale, construct landscape ecological security pattern and analyze urban spatial expansion mode, which can provide policy reference for the upcoming territorial spatial planning. Taking the coastal areas of Jiangsu as an example, based on the theory of ‘process-pattern’ of landscape ecology, this article constructs four single ecological security patterns for the maintenance of basic ecosystem services such as landform, water conservation, biodiversity and recreational landscape. According to the ‘minimum-maximum constraint’ criterion, by overlapping mosaic operations, four different levels of comprehensive ecological security patterns are constructed, and the low security level zone that needs to be strictly protected, then the high security level that could be planned as a key development zone in future. Meanwhile, use MCR model, set up and compare the impact of different models on urban spatial expansion, such as ‘ecological security protection type’ ‘economic growth dominant type’ and ‘ecological and economic coordination type’. The results show that the coordinated model of ‘ecological protection and economic development’ can better balance the ‘ecological-social-economic’ benefits. This model can reasonably determine the space for urban construction and industrial development. It is the optimal model for the orderly and healthy development of cities and towns in the future, and also of great significance for optimizing the spatial layout of cities and towns and improving the comprehensive benefits of construction land development.

Key words: landscape ecological security patterns, urban space, expansion model, the coastal area of Jiangsu
