The science-reasonable evaluation index system has been regarded as the core of land intensive assessment, and the relative studies mainly focused on monomer evaluation index system, including region-based construction land, urban construction land and development zones and so on. Differences between them needed to be studied. Methods employed included documentation and comparative analysis. By analyzing and comparing similarities and the differences between the monomer evaluation index systems, the paper put forward the ideas of constructing multi- level evaluation index system, including region, urban, development zones, education land of colleges and rural housing, which could improve the evaluation index structure layer. The conclusions had two aspects: firstly, significant similarities were presented in the aspect of connotation expression, selection of evaluation index and design of index system; secondly, the paper innovatively put forward the ideas for construction of multi-level evaluation index system and the core indicators system.
Freshwater cycle is the major environmental factor for four ecosystems including slope vegetation, river, lake or wetland and estuary in watershed scale. Variation of hydrological cycle will affect each ecosystem to different extent. By analyzing ecosystem’s process, structure and function, the impact assessment research both at home and abroad for how hydrological cycle affect ecosystem was summarized in this article. The article also indicated that in China more and more extensive water resources’ development by the government has changed hydrological cycle obviously and future economic development needs both water resources and healthy ecosystem. They will make the study on ecological impacting assessment caused by hydrological cycle variation in watershed become more desired. The main problems were summarized as follow: a) There is a lack of original biological information; b) Processes between hydrology and ecology in aquatic ecosystem are not clear enough; c) Influences of artificial controlling for ecosystem restoration are ignored. The main suggested methods are to construct ecological basis in different area based on limited ecological monitoring station, enhance research on eco-hydrological process and take dynamic assessment for different ecosystems.
