The paper analyzed and did research to the city land intensive land use, and took building project of the new Hefei station (high-speed railway station) passenger terminal and Binhu century city for examples, discussed the detail mode of city land intensive use, and got economical and social results.
In this paper, taking the northern region of Changxing County for example, with ammonia nitrogen as a pollution assessment index, we used an improved export coefficient method for estimate polluting load of non-point source pollution (NSP) and the social pollution survey data in the study area to estimate point source pollution. By comparing the total pollution output and the national surface water...
Eco-city as an inevitable choice of the Strategy of Sustainable Development had been much attention and admiration, which reflects the integration and coordination of industrialization, urbanization and modern civilization. The land took the ecology urban construction the carrier, were playing the foundational role and the crucial function in the ecology urban construction process. This article analyse...
With remote sensing data and GIS, the classification system of land landscape in the typical area of the Hanjiang River Basin is established. Using the indexes of the landscape pattern index and the ecological value index (EVI),this article presents the dynamic change of the landscape pattern from 1986 to 2006. The results showed that: (1)There is a dramatic staggered change. From the year of 1986...
This study applies GIS and RUSLE to analyzing the soil loss characteristics of Kyirong County in Tibet. The results show: (1) the R value is about 212.95 MJ·mm/(hm2·h·a). (2) average K value is about 0.332 t·hm2· h/(hm2·MJ·mm). (3) The average slope length is about 954.60m. And the average LS value is about 0.49. (4) the average annual soil loss of Kyirong County is about 4157.38 t/km2·a which is...
This paper supplies academic reference and scientific base for grain supplying security sustainable development and regional land use optimization by means of land use change and exploration into non-agriculturalization of land in traditional agricultural region in the North China Plain from 1979 to 2000. Constructed non-agriculturalization of land evaluation model and gained land use data by application...
Through the methods of change rate, dynamic degree index and transfer matrix, land use changes were analyzed, based on the land use data in 1980s and 2000. The major results could be summarized as follows: (1)A large amount of grassland, water body and barren land were transferred to forest land in 1980s–2000 in this region, because of the ecological protection and forestation. (2)Land use changes...
