农林作物土地适宜性评价是以农林用地为对象,以农林作物对农林用地的质量要求为标准,进行对照衡量,从而得出适宜、次适宜或不适宜种植某一农林作物的面积和分布,为土地利用规划、调整作物布局提供可靠的科学依据.当前国内外的土地评价中,涉及农林作物与土地因子关系时,往往采用定性的方法,或者采用等量的办法(即同等重要办法)来处理.我们认为这种办法缺少科学依据,不能确切回答土地因子在作物生长过程中所起的作用上的差别,而这种差别在很大程度上影
Land suitability assessment of agricultural and forestry crops is based on the use of land for agriculture and forestry, taking the quality requirements of agricultural and forestry land for agriculture and forestry as the standard, and comparing the area and distribution of the suitable, sub-suitable or unfit planting agricultural and forestry crops for Land use planning and adjustment of crop layout provide reliable scientific basis.At present, domestic and international land evaluation often involves qualitative methods or equivalent methods (ie, equally important measures) when it comes to the relationship between agricultural and forestry crops and land factors In our view, this approach lacks a scientific basis and can not give an exact answer to the difference in the role played by the land factor in the growth of a crop, which is to a large extent affected
