Abstract 【Objective】 Crop suitability evaluation is an important means for production zoning. This paper developed a new evaluation model of the ecological suitability for maize planted in mountain farmland, according to climatic, soil and topography condition. 【Method】 An evaluation index system of maize ecological suitability were selected after a systematic and comparative analysis of literature reviews, and 18 eco-environment factors were involved in the system. A climate model was established by the method of agricultural modeling based on the climatic conditions of maize growth period and ecological efficiency. The membership function method was used to calculate the suitability index for numerical and conceptual indicator variables, respectively. Expert scoring and analytic hierarchy process were used to determine the weight of each factor. Combining the weights and evaluation function, a new evaluation model was constructed to evaluate the suitability of climate, soil nutrient, site conditions, land management, and comprehensive ecological suitability. According the stereoscopic character of mountain farmland, evaluation units were divided by land using, soil type, and administrative division. The values of 18 indicators were calculated by GIS spatial analysis and attached into evaluation unites. Using the evaluation model and spatial data, the maize ecological suitability was evaluated for each class respectively or comprehensively. 【Result】 This method was used to evaluate maize ecological suitability in Xundian county, where the cultivated land was divided into 8 415 evaluation units. The suitable and high suitable area in climatic condition, soil nutrient, site condition, land management accounted for 58%, 86%, 42%, and 90%, respectively. The suitable and higher suitable area of maize planting accounted for 50.6% and 35.4%, respectively, which mainly distributed in the middle-southeast low-middle hilly area, and some in the central and northern Jinsha River valleys and western valley trough areas. The barely suitable and unsuitable area accounted for 9.4% and 4.6%, which mainly distributed in the northwest and some in the west of the central part. 【Conclusion】 This method was able to response the climatic difference during maize growth period and the stereoscopic character of mountain farmland. The suitability area distributed as fragments. The results were consistent with the regional situation basically. The climate and terrain were primary limit factors for the ecological suitability of maize in the region. Keywords:GIS;maize;ecological suitability;evaluation;Xundian county

DOI:10.1016/j.ejrs.2016.02.001URL [本文引用: 1] To reduce the human influence on natural resources and to identify an appropriate land use, it is essential to carry out scientific land evaluations. Such kind of analysis allows identifying the main limiting factors for the agricultural production and enables decision makers to develop crop managements able to increase the land productivity. Objectives of this study were to develop a GIS based approach for land use suitability assessment which will assist land managers and land use planners to identify areas with physical constraints for a range of nominated land uses. Georeferenced soil survey data and field work observations have been integrated in a GIS based land use suitability assessment for agricultural planning in Chamarajanagar district, Karnataka, India. Also, GIS has been used to match the suitability for main crops based on the requirements of the crops and the quality and characteristics of land. Different land quality parameters, viz. soil texture, depth, erosion, slope, flooding and coarse fragments under various land units were evaluated for the crops. Subsequently all of them were integrated using a sequence of logical operations to generate land suitability and capability maps. Suitability and capability maps for each land use were developed to illustrate these suitability degrees and display the spatial representation of soils suitable for agriculture. It was also found that better land use options could be implemented in different land units as the conventional land evaluation methods suffer from limitation of spatial analysis for the suitability of various crops.

Agriculture Land Suitability Evaluator (ALSE): A decision and planning support tool for tropical and subtropical crops , 2013,93:98-110. DOI:10.1016/j.compag.2013.02.003URL [本文引用: 1] Agricultural land suitability evaluation for crop production is a process that requires specialized geoenvironmental information and the expertise of a computer scientist to analyze and interpret the information. This paper presents ALSE, an intelligent system for assessing land suitability for different types of crops in tropical and subtropical regions (e.g. mango, banana, papaya, citrus, and guava) based on geoenvironmental factors that automates the process of evaluation and illustrates the results on an attribute table. Its main features include support of GIS capabilities on the digital map of an area with the FAO-SYS framework model with some necessary modifications to suit the local environmental conditions for land evaluation, and the support of expert knowledge through on spatial tools to derive criteria weights with their relative importance. A dynamic program for calculation of eigenvalues and eigenvectors of a weighting matrix is provided. Expertise and knowledge help ensure that ALSE databases represent realistic, practicable and functional systems. It is useful for decision makers to determine the quality of land for agricultural uses and is intended as a decision and planning support. Responsibility for any decisions based partly or wholly on the output of ALSE rests with the decision maker. ALSE ensures that the results are interpreted correctly within the relevant context, and contributes by maximizing land-use planning and decision support. (C) 2013 Elsevier B.V. All rights reserved.
