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。
In order to make full and rational use of abundant rubber land resources in Zhuozhou City, the suitability of rubber land is evaluated by GIS and mathematical models. The results show that Danzhou rubber area of 171,100 hm2, accounting for 67% of the city’s total area of agricultural land. The quality of rubbery land in the whole city is generally good, among which rubber is the most suitable, suitable and sub-optimal land area is 60,800 hm2, 691,000 hm2 and 41,200 hm2, accounting for 35.55%, 40.39% and 24.07% of the rubber land area respectively; Wind damage, drought, waterlogging, barrier gravel and so on, and poor soil nutrients are the main limiting factors for Danzhou rubber land use.
