The indicator of hydrologic alteration (IHA) and coupled with the range of variability approach (RVA) are usually used to evaluate the alteration of the long-term hydrologic flow regime for instreams, which is widely recognized and applied both in China and abroad. This study is intended to assess the hydrologic regime alteration of Hanjiang River induced by Danjiangkou Reservoir. In which, the record...
Taking the Northeast as the example, this paper put forward a model for evaluating regional sustainable development capacity which was based on ecological footprint method. The result was shown that ecological footprint per capita, ecological carrying capacity per capita and ecological deficit per capita were still rising up, it indicated that the Northeast was in unsustainable development. But GDP...
Spatial heterogeneity is the fundamental attribute of landscape and the reason for landscape elements generating matter flow and energy flow. On the basis of the distribution of aquatic vegetation landscape in Honghu Lake, we have carried out exploratory applied research on the method of landscape anisotropy. We determine the directions of anisotropy at a center-emanative and radioactive angle, and...
The ecological footprint (EF) analysis is a quantitative method to assess the sustainability of regional development. On the basis of the theories and methodology of EF, the procedure and the relevant models were developed for estimating the cumulative changes of ecological capacity caused by sea reclamation. And then they were applied to the case study of Xiamen Western Bay based on the calculation...
The sustainable urban development research is a hot spot in science, economics, society etc. The Ecological Footprint (EF) method, which originally developed by Wackernagel and Rees in the mid-1990s, is a useful approach to detect the sustainability of the city. The Ecological Footprint (EF) is a measure of human demand on the bioproductive land area that is required to support the resource demands...
Basing on multi-source remote sensing data, statistical data, supporting of GIS technology, this study carried out the research on comprehensive evaluation of the ecological environment quality of resource-based city - Panzhihua City from five aspects which is biological abundance, vegetation coverage, water density, land degradation and pollution load. The results show that the quality of the overall...
