Aiming at the problems existing in the current use of agricultural water and land resources in China and in order to realize sustainable use of the two resources, we established an indicator system for comprehensive evaluation of agricultural water and land resources carrying capacity based on the Driving forces-Pressures-States-Impacts-Responses (DPSIR) concept framework. Then we took Sanjiang...

planning of cities in order to respond to considerable needs of urban population, is one of the most important concerns of urban managers and authorities. urban development plans which have been provided to respond to these issues, have different objectives and characteristics. hence different plans are developed to plan and organize cities. most of these plans are being prepared without consid...

Ecological land is a land use category provided with considerable ecological value and a vital indicator reflecting regional eco-environmental quality. However, it has experienced severe fragmentation during the rapid urbanization in China which strongly threatened the regional ecological security, land use pattern and human living environment. Therefore, analysis of spatiotemporal change of ec...

Land use suitability assessment is an important fundamental work in urban-rural planning. Be restricted by technology and means, qualitative analysis methods be wider used in evaluating land use suitability in most districts of China. This method can’t impersonally and Quantitatively indicate the difference in land use suitability, and make urban-rural planning more subjectively because the inf...

This paper aims to develop a set of valid and reliable indicators to evaluate the regional land subsidence disaster vulnerability. The proposed indicator system can provide effective theoretical support for further land subsidence risk evaluation and risk management. This study transfers the qualitative analysis of land subsidence vulnerability to quantitative evaluation by developing a univers...

The arable land quality assessment system is developed with Visual C++ coupled with ArcGIS engine. The system can provide basic functions of geographic information system, for example, map browsing, overlay analysis, and spatial interpolation. The program has both single-factor evaluation module and comprehensive evaluation module, which evaluate the land quality by field sampling data and othe...

The present research aims to apply several approaches for suitability evaluation of lands under cultivation ofalfalfa and barley in Chaharmil mechanized farming center, Ardestan town, Isfahan province, Iran. Climatic andsoil maps of the climate and soil data were provided in raster format. Land evaluation carried out using maximumlimitation, parametric and multi-criteria (Analytical Hierarchy P...

In recent years, with the reforms to the land use system and the development of urbanization in China, land price evaluation has tended towards marketization. Prices are determined by the government, the land transaction market and the public. It is necessary to propose higher standards to be used in the evaluation process. This paper presents an online land price evaluation approach for conven...

using parametric approaches for qualitative assessment of land suitability is a useful method for diagnosis of land capability and potential in optimum crop production. by using such methods will hope that to achieve sustainability in based on fao land evaluation frame works and the presented tables of soil and climate requirements for agronomic crops. we studied qualitative land suitability fo...
