On the basis of introducing the status quo of land use in Luan County, the existing problems in the process of land use are analyzed as follows. First, the farmland is the majority, the area of garden land and forests is small and the farmland quality degenerates; second, the scale of construction use land is large, but me intensification level is low; third, reserve resources are scanty and the pressure of protecting farmlandmounts.
On the basis of describing characteristics and condition of application of natural growth model of population, weighted average growth model, regression forecast model and GM（1,1）forecast model, taking Gushi County in Henan Province as an example, according to the statistics of population in Gushi County Statistical Yearbook from 1991 to 2007, we establish four models to conduct fitting on population change respectively, and meanwhile, we predict population size from 2008 to 2009 and conduct preciseness test on the population size.
Extracting information about saline soils from remote sensing data is useful, particularly given the environmental significance and changing nature of these areas in arid environments. One interesting case study to consider is the delta oasis of the Weigan and Kuqa rivers, China, which was studied using a Landsat Enhanced Thematic Mapper Plus (ETM+) image collected in August 2001. In recent years, decision tree classifiers have been successfully used for land cover classification from remote sensing data.
Suitability evaluation of urban construction land based on geo-environmental factors is the process of determining the fitness of a given tract of land for construction. This process involves a consideration of the geomorphology, geology, engineering geology, geological hazards, and other geological factors and is the basis of urban construction land planning and management.
The Huang-Huai-Hai Plain is the most important winter wheat and maize production region in China. In response to the increasing population pressure, the Chinese authorities strongly invested in improving the irrigation systems and increasing ground and surface water exploitation within the plain to increase the crop productivity. This resulted in a reduction of water resource availability and in turn indirectly affected the suitability of various agricultural ecosystems in the plain.
This collection of analyses spotlight cases and interviews with prominent women activists involved in natural resource management in Nepal, Indonesia, the Philippines and China to better understand the diverse challenges faced by Asian women in relation to limited rights and insecure tenure. Despite contextual differences, the studies identify a number of similarities and trends.
This paper explores a 15-country household data base to evaluate the impact of three key assets (land, education and infrastructure) on rural poverty. Using both a descriptive analysis and a quadratic probit model, with the probability of being poor as a function of these three assets, the paper concludes that household access to education and infrastructure are positively associated with higher incomes, while the impact of land holdings varies across countries. Also, this paper shows the importance of the complementarities among assets in their poverty alleviating potential.
Most of the terrestrial biodiversity within the Asia-Pacific region is contained within forests. Protected areas are the mainstay for biodiversity conservation although other forest areas are also important. Habitat destruction and extraction of high-value species are major threats to biodiversity. Ecosystem stability is based on interdependence among constituent species and with biodiversity loss, resilience to change is reduced. Awareness raising, stringent environmental impact assessments, and improved law enforcement are required.
Based on me data concerning detailed survey on land in the year 2009 and land change in the year 2010 in Rong County, a mountainous region of Sichuan Province, by using quantitative geographical model, we conduct quantitative analysis of the status quo of land use in Rong County in terms of land use diversification, land use centralization, land use combination type, land use geographic significance and comprehensive use degreeof land use. m e results show some characteristics as follows.
