| 摘 要： | 为了探明赫章县耕地种植半夏的适宜性,促进赫章县农业结构优化及半夏产业稳步发展,以赫章县的耕地为研究对象,根据半夏生长与环境条件的关系,运用ArcGIS 9.3和县域耕地资源管理信息系统4.0软件,在确定半夏生态适宜性评价因子和评价单元的基础上,采用加权指数法构建模糊综合评价模型,对赫章县半夏生态适宜性进行研究。结果表明:赫章县高度适宜、适宜、勉强适宜和不适宜种植半夏的耕地分别占全县总耕地面积的6.82%、63.6%、24.85%和4.73%;不适宜种植区土体浅薄,质地粘重,土壤有效磷等养分含量中等偏低。

| Abstract: | In order to explore the suitability of P.ternata in Hezhang County,promote the optimization of agricultural structure and stable development of P.ternata industry,taking the arable land in Hezhang County as the study object,based on the relationship between the growth of P.ternata and the natural condition,the ecological suitability of P.ternata in Hezhang County was studied by using ArcGIS 9.3 and County Level Arable Land Resources Management Information System 4.0.The results showed that the arable land in the research area was divided into highly suitable area,suitable area,barely suitable area,and unsuitable area for P.ternata planting in Hezhang County,accounting for 6.82%,63.6%,24.85% and 4.73% respectively.Among them,the soil layer was quite thin,the texture was of heavy clay,and the nutrient content such as available P was medium low in the unsuitable area. |
