Residential environment design should pay attention to correctly involving cultural feature and environmental and ecological elements which should be integrated in certain living environment through a good design method, so as to reflect landscape designers’ concern on the urban living space. Taking the buildings of Urban Paradise (Paradise in Chinese literature is also called Taohua Yuan, that is, Land of Peach Blossom, originated from the essay by TAO Yuan-ming in the Eastern Jin Dynasty) in Nanning City for example, the research investigated how to integrate ecology and culture in the environment creation of residential district.展开更多

This study absorbed the essence of Chinese local ecological of the residential environment, for the use of contemprorary design. Through the practice of residential planning in Subu Town of Anhui Province, based on the protection of rural environment, the research completed according to local conditions and strategies for sustainable development.展开更多

Owing to natural factors and human activities, especially excessive reclamation from lakes, the shrinking process of the lakes has been accelerated. Wetland ecosystem has shown the characteristics of vulnerability. According to the analysis of wetland ecological function in the Jianghan Plain, this paper presented an index system related to productivity, stability and environmental capacity. By using the method of Analytic Hierarchy Process, we computed the values of the relative weights of the indexes, and evaluated the vulnerability level of the wetland ecosystem by the method of multi-indexes. The case study showed that the fragile extent of wetland ecosystem in the Jianghan Plain is 5.6. This means that the wetland ecosystem in the Jianghan Plain is laid to the state of middle vulnerability. Therefore, the wetland conservation and eco-rehabilitation in the Jianghan Plain should be paid attention to.展开更多
