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...

Traditionally, potential evaluation methods for farmland consolidation have depended mainly on the experts’ experiences, statistical computations or subjective adjustments. Some biases usually exist in the results. Thus, computer-aided technology has become essential. In this study, an intelligent evaluation system based on a fuzzy decision tree was established, and this system can deal with nu...

This paper established evaluation index system of comprehensive utilization of land from the three aspects of economic benefits, ecological benefits and social benefits. Firstly, ridge regression (RR) is used to the indicator index system for screening, and then genetic algorithm and support vector machine (that is GASVM) is trained to the transformed samples. Moreover, the comprehensive evalua...

The increasing amount of free and open remote sensing data suggests that a number of multitemporal land use and built-up land datasets derived from remotely sensed imagery will be made available soon. However, little research has been done regarding the approaches to evaluate spatiotemporal uncertainty of such products. Employing publicly available cadastral data with information on constructio...

Over recent years, remotely sensed data and spatial analysis techniques by providing timely and relatively inexpensive information, has proved useful for inventorying and motoring of widelife habitat in protected areas. To investigate on land cover pattern and the land use change in the Pendjari Biosphere Reserve , a time series of satellite imageries including LANDSAT TM and SPOT XS were used ...

  Application of gepraphic information system and image processing in evaluation of surface runoff of a watershed in recent years has increased greatly. In the study , the runoff curve number map was prepared using geographic information system (GIS)and Landsat Sattelite Images (ETM+)for two watersheds of Mansourabad in southern Khorasan province and Navroud in Gilan province based on the facto...

Crop-land suitability analysis is a prerequisite to achieve optimum utilisation of the available land resources for sustainable agricultural production. The Food and Agricultural Organisation [FAO, 1976. A framework for land evaluation (Soils Bulletin No. 32). FAO, Rome.] recommended an approach for land suitability evaluation for crops in terms of suitability ratings from highly suitable to no...

As the land ecosystem provides the necessary basic material resources for human development, land ecological security (LES) plays an increasingly important role in sustainable development. Given the degradation of land ecological security under rapid urbanization and the urgent LES requirements of urban populations, a comprehensive evaluation method, named Double Land Ecological Security (DLES)...

ecological capability evaluation and landuse planning can determine the best landuses and are important for the proper planning and sustainable development. there are various methods for ecological capability evaluation. in this research have been studied two methods (land use planning method with makhdoom ecological modsels) and (geomorphology method) for ecological capability evaluation in ne...
