目的:通过对怀山药道地产区河南省焦作市(古称怀庆府)温县、武陟县等县市的生态因子进行研究,分析与怀山药道地产区相似度高的区域。方法:以温县、武陟县等县市的样点为基点,利用中药材产地适宜性分析系统(TCMGIS-II)对该道地产区的287个采样点的1月均温、7月均温、年均温、相对湿度、年降水量、年均日照时数及土壤等7个生态因子进行综合分析。结果:(1)怀山药道地产区的生态因子值最适范围:1月均温-0.31~-0.12℃;7月均温27.07~27.19℃;年平均温19.76~19.88℃;相对湿度65.54%~66.26%;年降水量727.81~737.98 mm;年均日照时数2203.32~2215.16 h;土壤以潮土、脱潮土等土壤类型为主。(2)与怀山药道地产区生态因子相似度95%~100%的地区包括河南省东北部、山东省西部、河北省西南部等地区。结论:本文利用TCMG IS-II系统对怀山药道地产区的生态因子进行了科学的分析,并对怀山药的种植进行了初步规划,为怀山药的生产区划和合理布局提供了科学依据。
OBJECTIVE: To study the ecological factors in Wenshan City (Henan Province), Wenshan City (Henan Province), Wenxian County and Wu County and to analyze the similarities with the real estate of Huayama Road. Methods: Based on the samples of Wenxian County and Wuhu County, the average temperature of January and July of 287 sampling sites in the real estate area was calculated using the TCMGIS-II system. Temperature, annual average temperature, relative humidity, annual precipitation, annual average sunshine hours and soil were analyzed synthetically. Results: (1) The optimum range of ecological factors in the real estate of Huayama Road was January average temperature -0.31 ~ -0.12 ℃, average July temperature 27.07-27.19 ℃, annual average temperature 19.76-19.88 ℃ and relative humidity 65.54% ~ 66.26%; annual precipitation 727.81 ~ 737.98 mm; average annual sunshine hours 2203.32 ~ 2215.16 h; soil with soil, off-soil and other soil types. (2) The areas with similarity of 95% ~ 100% of the ecological factors in the real estate of Huayama Road include areas in northeastern Henan Province, western Shandong Province and southwestern Hebei Province. Conclusion: In this paper, TCMG IS-II system was used to make a scientific analysis of the ecological factors in the real estate of Huayama Yaodu. The preliminary plan was made for the cultivation of the yam. It provided a scientific basis for the production division and rational distribution of the yam.
