Quantitative Analysis of Ecological Effects Caused by Master Planning in Hilly Area: A Case Study of Kunming Expo Eco-town, China

摘要

The environmental conflict throughout land development varies for every landform. In hilly areas, the ecological effects, such as the properties of the land surface and the diversity of flora and fauna cannot be reflected through assessment indexes, which include the building density, green areas ratio, etc. This paper is to provide the impervious index and the corridor index as a complement to the master planners. The indexes is an approach that integrates ecological landscape principles and methods for analyzing the eco-rationality of the master planning using ecological indexes which provides a measure for adjusting development density. An application of the indexes to the residential development of Kunming Expo Eco-town in Yunnan Province, China is provided. The result shows that the indexes can be used to quantify the interrelationship between the development project and the environment and that the required regulatory measures for land development can be implemented via master plans.
