To better manage common-pool resources, planners and conservation specialists continue to call for comprehensive and spatial planning functions of local governments to focus on entire ecological units rather than areas defined by jurisdictional boundaries. Local comprehensive plans were quantitatively analyzed and case studies were conducted within an urbanizing lake watershed to determine how well...
In recent years, the study on ecosystem service value is paid more and more attention. In this paper, the region around the Dianchi Lake was chosen as the study area, for the reason that the region demarcated by the border river basin was rarely studied in simulation of ecosystem service value. The study was done with GIS technologies such as spatial statistical analysis technology in the following...
With regard to the increasingly prominent issue of cultivated land protection, it is necessary to establish a fast and effective early warning system that can have a real-time monitoring on cultivated land protection status. This thesis takes urban fringe area with prominent changes in cultivated land as the survey area, on the basis of comprehensively application database, System Dynamics (SD) and...
The water-level-fluctuating zone (WLFZ) in the Three Gorges Reservoir (TGR) changes seasonally because of the special hydrological characteristics and agriculture practices. Rapid land use changes have taken place in the WLFZ of the TGR, which is affected by the functions and structures of the local environmental system directly or indirectly. Land use change analysis is very important for land planning...
In the process of rapid urbanization, urban land use cover was changed by human activities. In order to maintain sustainable development in land use, it is very important to study dynamical characteristics of land use and the processes of land cover changing in urban region. As a case of Huadu district of Guangzhou, temporal and spatial characteristics of land use in 1990-2005 were analyzed with remote...
The land use and land cover changes have been issues for better understanding human-land relations and sustainable development of regional land sources. This paper was to analyze the land use and land cover changes in new land around Bohai bay with crisp ecosystem and fast development during last 20 years with RS and GIS taking Guangrao county as a case study. In this study, two Landsat TM images...
In the Paper, the research range is Poyang lake area which is important position in the middle-lower reaches of Yangtze river and Jiangxi Province. Based on the RS and GIS technology, the paper uses Delphi method to determine the land use types eco-system service unit value, to study the relationship between land use change and eco-system service value. With the collected material, the paper adopts...
The National Ecological Observatory Network (NEON) is a continental-scale research platform for discovering, understanding and forecasting the impacts of climate change, land-use change, and invasive species on ecology. Site-based flux tower and field measurements will be coordinated with high resolution, regional airborne remote sensing observations. This data combined with satellite observations,...
CLUE-S (the Conversion of Land Use and its Effects at Small Region Extent) Model was used to predict land use and land cover change (LUCC) from 2001 to 2020 in Zhangye City. The modeling built 3 kinds of water amount restriction scenarios. The base map was the land use map from TM image of 2001. 10 kinds of important driving factors of LUCC were chosen by Arcview 3.3. The weighting coefficient of...
Land demand is one of the key elements of Shanghai development, and wetland or tidal flat exploitation is the main way to land increase in Shanghai. Here comes an issue of the double-win between wetland exploitation and protection. A compensation mechanism for wetland loss is established in this paper, and a fuzzy decision-making chain is put forward with the example of the wetland in Shanghai.
The Pressure-State-Response model (PSR) proposed by the OECD and UNEP in 1994 was used to evaluate ecosystem health, In this paper, the PSR concept model was cited to reflect the pressures upon land resource in different time exerted by human activities, the responses of society to these pressures, and the state changes of land resources in different phase. A workable indicators system of PSR model...
Land use change models are the important tools in researching regional landscape dynamics and its driving mechanisms. Researchers have aimed at exploring land use/cover change (LUCC) and predicting future land use pattern in order to improve our understanding of the causes and effects. With the application of CLUE-S (Conversion of Land Use and Its Effects at Small Regional Extent) model and under...
Ecological security is the core and basis of sustainable land utilization. Study of land ecological security has become a forefront area in study of sustainable land utilization. Based on Pressure-State-Response model, the paper constructed an evaluation index system of land ecological security. The index system was composed of land resource pressure, land resource state and cultural environment response...
Evaluation of land ecological safety plays an important role in regional economic development, reasonable land utilization and ecological construction. The paper constructed an evaluation indicator system of land ecological safety. The indicator system was composed of natural, economic and social elements. Then the paper established an evaluation model of land ecological safety based on ordered division...
The South Florida Ecosystem Portfolio Model (EPM) prototype is a regional land use planning web tool that integrates ecological, economic, and social information and values of relevance to decision-makers and stakeholders. The EPM uses a multi-attribute evaluation framework that builds on GIS analysis and spatially-explicit models that characterize a wide array of important ecological, economic, and...
Land is vitally related to human existence and development. It has being evidently proved that sustainable utilization of land resources is the core problems of sustainable development. Taking Beijing city as a model case, we used the Delphi and Analytic Hierarchy Process (AHP) methods to assess the land intensive use level from 1996 to 2005. By building respective index system of intensive land use,...
Natural and anthropogenic (e.g. land cover/land use change) processes can lead to ecosystems change dramatically on timescales from years to decades. Especially, land cover/land use changes by mining can have drastic impacts on ecosystems and basin-wide water budgets. Phosphate rock is an important strategic resource. China and U.S. are two major phosphate reserves counties in the world and both facing...
Human activities on land-use make the land-cover gradually change or transit. With the GIS/RS technique, the paper studies the ecosystem service values change in Qianjiang City which is begotten by land use change. The results shows that the ecosystem service values shows an upward trend, and the land use structure is more reasonable.
The subsided land of mining area is not only the land and ecological environment damage caused by the exploit of mineral resources but the very important land resource to sustainable development of the resource-based cities. A view is put forward that the ecological reconstruction of collapsed land of the resource-based cities should be planed based on its zones. Taken the Pingdingshan City as a case,...
Soil and terrain digital database (SOTER) recognizes the regional land according to terrain, rock, and soil providing a comprehensive framework for the data storage and retrieval. Currently SOTER has been authorized and become one of hotspots in the studies of soil and sustainable use of land. Combining SOTER and LUCC, taking SOTER units as the frame of LUCC information, constructing SOTER-LUCC database...
