In this article, artificial wetland and landscape river were used to build the water circulation system to maintain and improve the quality of urban landscape water and to prevent water eutrophication. According to the Liebig law of the minimum, it could be determined that TP played an important role in the process of eutrophication and TP (total phosphorus) was the primary constraint condition to...
From the perspective of "human", this study focuses on the feeling of people in a certain region about the waterfront environment, by combining with theories in landscape architecture, environmental psychology and other interdisciplines, in view of present situation of waterfront landscapes in the Yellow River Scenic Area of Zhengzhou City, tries to find new approaches for waterfront landscape...
This study aims to assess the groundwater pollution potential by Beheshte Zahra Cemetery, Tehran, Iran. Surly there is the penetration of decomposition products into seepage, during the fate of human corpses. This seepage contains bacteria, viruses and organic and inorganic chemical decomposition products. In this investigation, analyzing the data gathered about Beheshte Zahraha has been done; the...
Indigenous lands represent an efficient way to protect indigenous communities and environment in Brazil. However, these lands are also highly affected y the land use changes occuring in its surroundings. We quantified the land use changes in the Xingu basin based on MODIS EVI data between 2000 and 2006. We estimated the deforested area inside and outside the indigenous lands, the crop expansion and...
Nonpoint source (NPS) pollution has become one of the biggest challenges in maintaining water quality and aquatic ecosystems. However, the impacts of topography, land use change, human activities, precipitation etc., make the modeling and control of NPS pollution in temporal and spatial scales difficult. In recent years, the rapid development of Remote Sensing (RS) and Geographic Information System...
Groundwater pollution risk assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating groundwater pollution risk assessment by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of...
Formed by the stacking of solid waste from the coal industry emissions, the coal gangue dump brought about a series of ecological and environmental problems, such as the decrease of the quality of the air, surface water, groundwater and soil, ecosystem degradation, the losing of species diversity, the damage of landscape and the yield reduction of crops and so on. Therefore, the purpose of governance...
A case study on the impact of land use/cover change on shallow groundwater quality in the oasis over the Sangong River Basin, Xinjiang, China, is carried out by applying RS, GIS and geostatistical analysis. The data used in this study include the TM images in 1987, ETM images in 2004 and test data of groundwater quality sampled from 77 wells in 2004. Results indicate that the hydrochemical characteristics...
This paper discusses the factors influencing the overall structure and layout of the planning of land reclamation, proposes a multi-objective and multi-level comprehensive evaluation index system for the planning of land reclamation based on fuzzy thoughts, and then establishes a multi-objective decision-making model. The paper also uses concrete examples to illustrate the index system is rational...
In this paper, the author taking the geological problem of environment and occurred geological disasters evaluating objects, apply GIS HAP to evaluate three subsystems of rock environment, environmental soil, water environment which affect the quality of geological environment of Wuhan megalopolis. By analyzing the main factors which affect the subsystems, the author establishes subsystem hierarchy...
Geoinformations technology and multivariate statistical analysis method were coupled to reveal the response of water quality to land use pattern in Jiulong river watershed, the second largest watershed of Fujian province with intensive agricultural activities. The study results obtained show that in entire watershed level, arable land (ALU) is the most important factor influencing DO in stream, moreover,...
It can serve for the city planning scientifically and improve the people's knowledge about the detailed surroundings by evaluation of urban environment status from high resolution satellite images. Environmental factors such as vegetation type and coverage, water area and water pollution can be known from the images directly, the population density can be calculated from the building structure, the...
This research aims at to assess the impact of natural hazards on the human activities and development planning held along the eastern coastal stretch of the Gulf of Suez. Change detection technique was used in combined with geologic and topographic maps, GIS and field investigations to specify and categorize environmental hazards along the concerned area. This site is characterized by enormous natural...
