摘要
探讨了土地生态规划与设计的原理、基本原则和方法。在对原理、基本原则分析基础上,提出土地生态规划与设计的方法。它是根据景观生态学原理和系统理论,以GIS技术为支撑,对区域土地利用系统土地利用类型数量结构进行了优化,计算和分析了土地利用空间格局的特征指标(景观多样性指数,优势度指数,均匀度指数,破碎度指数,分维指数,廊道密度)。在基本原则指导下,以土地生态评价和功能分区为基础,对土地利用空间格局进行调整配置,并对典型景观单元进行土地利用模式设计,以形成高效土地利用模式,实现土地可持续利用。最后对山海关区进行了案例实践。
This paper discusses the theories, the basic principles and methods of the ecological planning and design of land. 2 theories and 5 principles are concerned. Based on the theories of landscape ecology and system, this paper optimums quantity allocation of land use, calculates and analyses landscape indexes of the special pattern, the landscape diversity, the landscape dominant index, the landscape homogeneity index, the landscape broken index, the landscape patch fractal dimension, corridor density by GIS ARC/INFO. Through the analysis of land use functional region and land suitable eco-evaluation, authors rearrange the spatial pattern of land use, and design typical landscape unit land use in order to create high-effective land use model and sustainable land use. Finally, Shanhaiguan region is chosen as a case study.
