In recent years, researchers pay increasingly attention on river ecological restoration at home and abroad. According to the practical situation of Tianjin Airport Economic Park river water environment and inter-external experiences, several ecological techniques, such as phytoremediation, artificial aeration and ecological riverbank, were adopted to river ecological restoration. And related operation...
The harmonious development of the college campus in China is challenged by the rising number of bicycles as well as low bicycles operating factor, meanwhile the call for eco-campus and low-carbon campus provokes an efficient and ecological trip mode - public bicycles. Through the investigation of 12 typical universities in China, the outlines of students traveling behaviors is studied. Starting from...
The State-owned forestry enterprises have made tremendous contributions to China's economy development. Under the system of planning economy, these enterprises have provided the main production element, huge profits and taxes for China's construction. It considered that the state-owned forestry enterprise is a special complex of economic, ecological, social and resource's property, its sustainable...
A system of wetland monitoring and Eco-health assessment has been set up based on 3S. The system is be made up of information management subsystem, assessment subsystem, prewarn subsystem, other management subsystem. Taken Huixian wetland of Guilin as the object of study, the system made to operating, the result show that the wetland state of health is bad, CEI=0.364. The building of the system is...
Wuhan city is the core city of Wuhan city circle and the major city of the Yangtze River, and the change of water have attracted great attention. Using the techniques of "3S" and landscape ecology, based on 1991 and 2009 Landast TM remote sensing image, integrating with the change of water modeling, transform matrix, the shift of gravity centers and landscape pattern analysis software Fragstats3...
Vegetation parameters are important to improve the performance of numerical weather prediction, global change monitoring, and ecosystem modeling. In the study, Discrete Anisotropic Radiative Transfer (DART) model is employed to simulate Bi-directional Reflectance Distribution Function (BRDF)of heterogeneous landscape scenes. The simulated BRDF is required to match the measured BRDF by the POLDER (POLarization...
Applying the theory of Industrial Ecology, the paper conducts a comparable research on the industrial symbiosis in the process of establishment of Eco-industrial Park (EIP). Through the analysis of the two examples: Kalundborg Eco-park in Denmark and Guitang Eco-park in China, we put forward two industrial symbiosis operational patterns: Individual Entity Symbiosis and Comprehensive Entity Symbiosis...
Governments, corporations and families around the world are seeking low-carbon and ecological economic growth pattern and life style amidst the post-financial crisis era. The essence of low-carbon economy is to fundamentally abandon human's dependence on fossil energy through technological and managerial innovation. Featuring in low energy consumption, low emission and low pollution, a sustainable...
On the research of contrastive analysis, this paper discusses the environmental impact of high-speed maglev and high-speed wheel-rail in land use, noise pollution, energy consumption, ecological effect, electromagnetic radiation and other aspects. On this basis, this paper describes the influences on environment of high-speed maglev in transit system of China, and puts forward the concrete opinions...
Based on remote sensing(RS) and geographic information system(GIS) technology, the land use range and landscape pattern index were used to study the spatial-temporal change of land use in Pingdingshan mining area, Henan Province, China. We analyze the change of the range and spatial pattern based on remote sensing images in 1978, 1994 and 2006. The results showed: 1) The regional landscape were changed...
This paper offers an in-depth examination of the strategy trend of development and macro-management of mineral resources in China should be dynamic management of reserves: moderate development of resources, strategic resource reserves, overall value increase of mining area, dividing-area management of mineral resources, regulation and optimization of mining structure and layout, paid use of mineral...
This article describes a concise way to estimate litter decomposition rate in a regional scope; Meanwhile, we proposed a new method for evaluating the rate of single/mixed litter decomposition in a forest ecosystem.
We choose main streams of Irtysh River and Ulungur River as river corridor and divide buffer strips at rate of 5 km from each riverside according to buffer strip analytic procedure, whose buffer strips are 10 km, 20 km, 30 km, 40 km, 50 km and > 50 km wide respectively. Subsequently we calculate and analyze index of main landscape pattern in terms of landscape and patches so as to reveal radiation...
A simple biosphere model (version 2, SiB2) is an ecological model with high simulation accuracy, which can be used to simulate the dynamic change of the fluxes of water, heat and carbon. This paper simulated the dynamic change of the fluxes of energy and CO2 by SiB2 based on the observational data from June 20, 2005 to October 9, 2005 in Weishan experimental station. The results showed that SiB2 was...
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 Northeast shelterbelt project is a part of the Shelter Forest System Program in Three-North Regions of China. By far, the third phase project has been completed, and the fourth phase project is on the point of completion. This paper chose the Yushu, Nong'an, Dehui and Fuyu in midwestern Jilin province as the research areas, selected three phase shelterbelt data and land use data at Sep. 25, 1988,...
We investigated the problem of river's Minimum Ecological Water Demand (MEWD) in Chinese mountain area on the premise of protecting the river hydrobiology's habitat and scientific operation of the reservoir hydropower station project. This paper uses Wetted Perimeter Method to determine the MEWD of the downstream of Maojiahe Reservoir dam, and compares the results from Tennant Method with that from...
Froude number expresses the combined effect of stream channel roughness and overall bend curvature (which slow down water velocity) plus the driving gravitational force that results from stream gradients. Through the research of Froude number at bend transitional shoal in Yangtze River, give a hydraulic condition in distribution of habitate patches.
The unrestrained exploitation of coal resources lead to severe environmental problems in resource-exhausted areas in China. The environmental pollution and ecological damage degree are the basis to the eco-environmental restoration, both to determine the scope and to calculate the investment. So in ecological damaged area, to evaluate the damage degree is more important than evaluate the quality....
Qinghai-Tibetan Plateau plays an important role in estimating net primary productivity of grassland ecosystem for global carbon cycling research. In this paper, boreal ecosystem productivity simulator (BEPS) model was modified according to the characteristics of grassland canopy. A hypothesis of horizontal homogeneity and vertical layer was put forward for grassland canopy and BEPS was modified to...
