In the paper, some relative research theory and calculation methods for the river ecological basic flow both at home and abroad have been summed up, and then, considering the actual conditions of Sushui River, the function of the river reach is determined. The ecological basic flow of the river in different periods has been quantitatively researched with Tennant and the minimum monthly average flow...
Eco-city research has been given close attention during the past decades, and the evaluation of it has become a key part. According to the research results of eco-city evaluation at home and abroad, an evaluation index system has been established, including resource and environment, economy, socio-culture and management. On the basis of the index system, fuzzy matter-element model is used to evaluate...
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...
With the accelerating process of industrialization, China is currently facing a series of resources issues, environment issues and social issues, environment, increasing pressure. If you do not take strong measures, energy conservation and environmental protection objectives may not be realized. In formulating economic and social development planning must follow the economic law and natural law, give...
Currently, urbanization has entered a stage of rapid growth in China, the environmental pollution and ecological destroy of cities are becoming more and more serious day by day. The work field of city planning and design is beginning to expand to undertake a task to improve living and ecological environment due to paying more attention to afforesting and ecological construction. Under the new background...
Based on the relevant literatures and theoretical analysis, this paper summaries the fundamental theories supporting for marine ecological compensation, including value theory of ecological environment, public goods theory, externality theory and sustainable development theory, and illustrates the necessity of applying marine ecological compensation into reclaiming land from sea. Then the paper discusses...
The exploitation of coastal beach plays a great role in promoting the development of local economy. The employment of different development modes of coastal beach will in different degrees influence local resources, environment, ecosystem stability, economic and social development and so on. Therefore, the choice of a scientific and rational model is particularly important to the exploitation of coastal...
This paper taking Mudanjiang in Heilongjiang Province as the study region, the remote sensing data and topographic map data in forth years as a basis for data, the vulnerability model was evaluated based on the sensitivity, exposure and adaption ability, relevant parameters of model was acquired by GIS and RS technology and mathematic model, and the vulnerability of ecological environment was in a...
To monitor the land sandy desertification dynamic change accurately in Duolun, the desertification was classified and evaluated based on the land use point of view and the evaluation index system based on land use was set up. TM image was decomposed by linear spectral mixture mode and the vegetation component of TM image was amended by the high-resolution satellite image to extract the information...
A free trade zone (FTZ) or a export processing zone (EPZ) is an area where some traditional trade barriers such as tariffs and quotas are eliminated and bureaucratic requirements are lowered in order to attract more business and foreign investments. In this paper, eco industry theory is applied to a FTZ named Waigaoqiao Free Trade Zone (WFTZ) in a unique city Shanghai to look for its sustainable development...
Acid rain can bring a lot of damage to the ecological environment of the earth and social economy of human. Studies show that acid rain is harmful to soil, waters, forest, buildings and scenic spots. It not only brings heavy economic loss, but also affects the survival and development of human severely. The SO2 in the atmosphere is the leading source of acid rain. Now People pay more and more attention...
Biodiversity has become an internationally central concern. As such, it is crucial to fully consider it into social economy development. This paper explores how to carry out the biodiversity impact assessment (BIA) as a useful tool for biodiversity conservation. Taking Beibu Gulf economic zone as the case, the study predicts the impact of the industrial development plans for the period 2007-2020....
The indicator of hydrologic alteration (IHA) and coupled with the range of variability approach (RVA) are usually used to evaluate the alteration of the long-term hydrologic flow regime for instreams, which is widely recognized and applied both in China and abroad. This study is intended to assess the hydrologic regime alteration of Hanjiang River induced by Danjiangkou Reservoir. In which, the record...
Since 1997, Costanza and others assessed the value of global ecosystem services. The assessment methodology and the adaptability of the established methods have become the concern of academia. The paper assesses the four forest ecosystem services of Beibu Gulf in China, based on the services valuation methods, accepted by civil experts. These services include forest products, carbon sequestration...
The greater hinggan mountains in China is the green treasure, containing enormous economic, ecological and social benefits. However, due to the years of unreasonable deforestation structure, gradual degradation of the forest function and forest ecological environment hinders the mountains' development. Speed up constructing the mountains' ecological function areas becomes the primary task of promoting...
Bosten Lake, which locates in arid and desert zone, is the largest lake in Xinjiang, and is the largest inland freshwater lake in China. It has giant value in environment, ecology and economy. The water level of Bosten Lake has taken place tremendously in the recent 50 years, the water level descended from 1048m above sea level in 1958 to that of 1045m in 1987, and ascended from 1045m to 1048.9m during...
Sampling method was employed to investigate the structure and ecological benefits of street trees in the area within Second Ring Road of Shenyang. The study area covers about 161 km2, and 61 main roads. Based on the field data, the i-Tree (STRATUM) model was run to analyze street trees' structure and ecological benefits. The results showed that there were 19 street tree species in the study area,...
Using the closed chamber technique daily changes of net ecosystem carbon dioxide (CO2) exchange (NEE) and ecosystem respiration (Re) were determined in a ryegrass ecosystem on eight separated days at half hour interval from morning to afternoon in Taiyuan basin, Shanxi province of China. The gross primary production (GPP) was calculated as the difference of NEE and Re. The objective of the study was...
The contents and characteristics of ten heavy metals in surface sediments from Yangzonghai Lake in Yunnan, China were analyzed. Ecological risk index presented by Håkanson to assess the potential ecological risk of Yangzonghai Lake was utilized. The results showed that the average concentrations of titanium(Ti), manganese(Mn), zinc(Zn), vanadium(V), chromium(Cr), copper(Cu), nickel(Ni), cobalt(Co),...
Human capacity as well as institutional capacity and societal capacity determines the management capacity of the nature reserves. In China, the human capacity can not meet the requirements for the nature reserve protecting and the biodiversity conservation. This paper focuses on the current human capacity building in the nature reserves in order to promote their management effectiveness. We find that...
