摘要
为了充分合理利用儋州市丰富的橡胶土地资源,运用GIS与数学模型对橡胶用地适宜性进行评价。结果表明,儋州市宜橡胶用地面积为17.11万hm2,占全市农用地总面积的67%。全市宜橡胶用地质量总体较好,其中橡胶最适宜、适宜和次适宜用地面积分别是6.08万hm2、6.91万hm2和4.12万hm2,分别占宜橡胶用地面积的35.55%、40.39%和24.07%;风害、旱、涝、障碍层砂砾多、土壤养分贫瘠等是儋州市橡胶用地的主要限制因子。
The objective of the study was to use GIS technic and mathematic models in suitability evaluation of rubber land and further utilization of abundant rubber land resources in Danzhou. The results indicated that the total area of suitable land resources for rubber was 17.11×104hectares, accounting for 59.46% of agricultural land area. The land quality for rubber was overall good in Danzhou. The area of the most suitable land resources for rubber was 6.08×104hectares, and the more suitable was 6.91×104hectares, and the suitable was 4.12×104hectares, which accounted for35.55%, 40.39%, 24.07% of all the suitable agricultural land areas for rubber, respectively. Wind damage, drought,waterlogging, excess grit of soil obstacle layer and soil nutrient impoverishment were the main limited factors for rubber land in this area.
