Fruitful resources of solar energy in China have a huge prospect to development and utilization. In this paper, an elementary school classroom located in alpine region has been studied to estimate the potential benefits of solar energy used in house heating. The effectiveness of Warming in classroom with attached sunspace has been analyzed based on solar radiation received at unit area. Results show...
There is an obvious regional discrepancy in the ratio of energy consumption to agricultural production in China. First, the paper used the cluster analysis methods to divide Chinese 30 provinces into four regions. Then, a panel data model is used to analyze the relationship between agricultural production and it's energy consumption in the different regions. The results show that there are four linkage...
Dividing the Main Functional Regions on territory space is implemented in China, in order to identify the region units that are suitable to develop or protect. It is essential to coordinate the relationship between human and nature, so as to achieve the target of sustainable development. Gansu Province, which is located in the northwest of China, has large span in the geographic range. In this area,...
Land use/cover change (LUCC) is one of the core contents of the global change research. As a unique ecological unit in arid and semi-arid area, oasis is a basic premise to maintain the existence and development of local people. In this paper, the rectangular area, where Dunhuang oasis locates, is chosen to study the dynamic change of LUCC over the last 20 years. Landsat5-TM images of 1987, 1996 and...
The study on population and the resource-environment by the consumption may contribute to the further cognition about their correlations and provide the policy references for natural resources use and environmental protection. This article has studied the impact status of the consumption level difference of China's 31 provinces or autonomous regions on the resource-environment in 2005 by per capita...
Population distribution is provided with obvious dispersion and diversity speciality in hill and mountainous region there agriculture production is dominant. Analyzing population distribution on hamlet scale approaches fact much more. Improvements in remote sensing (RS) technologies and the use of geographic information system (GIS) are increasingly allowing us to probe into population distribution...
In order to evaluate the precision of hyperspectral reflectance model for monitoring soybean leaf area index (LAI), soybean canopy reflectance data collected with ASD spectroradiometers (350~1050 nm), which were cultivated in water - fertilizer coupled control conditions, and soybean LAI were collected simultaneously with LI-COR LAI-2000. First, correlation between reflectance, derivative reflectance...
Study on population distribution characteristics and regulations have realistic meanings for harmonizing human-land relationship, managing scientifically population, resources and environments. Improvements in remote sensing (RS) technologies and the use of geographic information system (GIS) are increasingly allowing us to probe into population distribution at multiple scales. This paper researches...
