根据琼海市实际情况筛选出该地区对胡椒种植影响最大的4类,11项指标,采用AHP法计算各评价因子的权重。结果表明,气温、土质和风力最为重要,权重分别为0.351、0.220和0.175;总磷对胡椒影响最小,权重为0.004;AHP法可以科学确定胡椒用地评价因子的权重。
According to the actual situation in Qionghai, four kinds of indicators and 11 indicators which have the most influence on the pepper planting were screened in this area. The AHP method was used to calculate the weight of each evaluation factor. The results showed that temperature, soil and wind were the most important, with the weights of 0.351, 0.220 and 0.175, respectively. The total phosphorus had the least effect on pepper with the weight of 0.004. The AHP method could scientifically determine the weight of the evaluation index of pepper land.
