土地(壤)评价是农业科学领域一项重要的基础工作。近年来,GIS技术被广泛用于农业用地作物种植适宜性评价,并已成为土地适宜性评价中重要的技术手段。作物适宜性评价是针对某种作物在特定地域种植的适宜性程度做出的结论性评价。客观评价耕地资源的作物种植适宜性,对于合理开发利用耕地资源、维护和提高耕地资源的作物生产力、保证县域农产品产量和质量供给具有十分重要的意义。
Land (soil) evaluation is an important basic work in the field of agricultural science. In recent years, GIS technology has been widely used to evaluate the suitability of crops for agricultural land use, and has become an important technical means in land suitability assessment. Crop suitability assessment is a conclusive assessment of the suitability of a crop for planting in a particular area. Objectively evaluating the suitability of arable land for crop cultivation is of great significance for the rational exploitation and utilization of arable land resources, the maintenance and improvement of the crop productivity of cultivated land resources and the guarantee of the output and quality of agricultural products in the county.
