摘要: 基于晋东南地区16个国家气象观测站1981—2018年的气候资料,分析了气候因子与潞党参产量的相关性。选取全生育期≥10 ℃积温和降水量、根生长期平均气温以及苗期降水量等主要影响因子作为生态气候区划指标,选取DEM和土壤质地作为地理环境影响指标,分别建立各指标的空间分析模型,按照90 m×90 m的细网格进行推算,采用隶属函数计算得到的各指标评判值以及熵权法确定的权重系数,构建了潞党参生态气候适生综合评判指标,对晋东南地区潞党参生态气候适生种植区进行了区划。结果表明:晋东南地区潞党参生态气候适宜区主要分布在东部太行山区、西部太岳山区以及晋城西南部的太岳山和中条山的交界处,区域内光温水资源匹配较好,适宜潞党参生长发育;较适宜区主要分布在太行山和太岳山向中部上党盆地和晋城盆地过渡的浅山丘陵区,该区域热量条件较好,降水资源相对短缺;不适宜区主要分布在上党盆地和晋城盆地的中心区域,区域海拔较低,夏季高温,不适宜潞党参种植。本研究结果可为晋东南地区潞党参优化生态布局,科学、合理利用气候资源提供参考。

Abstract: We analyzed the correlation between meteorological factors and the yield of Codonopsis pilosula based on the climate data from 1981 to 2018 of 16 national meteorological stations in southeastern Shanxi. Four factors were selected as the eco-climatic zoning indices, including ≥10 ℃ accumulated temperature and precipitation during the whole growth period, average temperature during root growth period, and precipitation during seedling period. The DEM and soil texture were selected as geographic environmental impact indices. The spatial analysis model of each index was established. These indices were calculated in 90 m×90 m fine-grid. Comprehensive evaluation index of eco-climatic suitability of C. pilosula was constructed based on the evaluation of each index calculated by the membership function and the weight coefficient determined by the entropy weight method. Climatic suitable planting division of C. pilosula in southeastern Shanxi was carried out. The results showed that the suitable area is mainly distributed in the Taihang Mountain in the east part of southeastern Shanxi, Taiyue Mountain in the west, and the junction of Taiyue Mountain and Zhongtiao Mountain in the southwest of Jincheng, with good matches of light, temperature and water resources. The subsuitable area is mainly distributed in the transitional shallow hilly areas from Taihang Mountain and Taiyue Mountain to Shangdang Basin and Jincheng Basin, with adequate heat but relative limiting precipitation. The unsuitable area is mainly distributed in the central areas of Shangdang Basin and Jincheng Basin, with low altitude and high temperature in summer. Our results can provide a reference for the optimized ecological layout of C. pilosula in southeastern Shanxi and the scientific and rational use of climate resources.
