摘要
[目的]为充分利用绥阳县气候资源,合理布局金银花种植区域.[方法]选取了年平均气温、年日照时数、日平均气温＜3℃天数、≥16℃天数和20～30℃天数以及5月平均气温作为绥阳县金银花气候适宜性区划指标,利用遵义市13个气象站1981～2010年的逐日气温和日照资料,基于绥阳县1∶25万的地理信息数据,采用梯度距离反比权重法对6个区划因子进行了空间插值;利用模糊数学方法,分别构建了各区划因子的隶属度函数和综合气候适宜度模型,按照适宜种植区、次适宜种植区和不适宜种植区3个等级完成了绥阳县金银花种植适宜性区划.[结果]绥阳县金银花种植的适宜区主要分布在海拔900 m以下的川道、坡塬,不适宜区主要分布在1 200 m以上的山区.[结论]冬季温度偏低、热量条件不足及日照偏少是制约全县进一步发展金银花种植的主要原因.
[Objective] To make full use of climatic resources in Suiyang County and to reasonably distribute the planting area of Lonicera japonica Thunb.[Method] Several climate suitability zoning indexes were selected for L.japonica in Suiyang County,such as annual average temperature,annual sunshine duration,the number of days with daily average temperature ＜ 3 ℃,≥ 16 ℃ and 20-30 ℃,and average temperature of May.Based on the 1∶250 000 geographic information data and the daily temperature and sunshine data in thirteen meteorological stations in Zunyi from 1981 to 2010,spatial interpolation of six climatic elements in grids was carried out by using the gradient plus inversedistance-squared technique.Fuzzy membership functions of six climatic elements and climatic suitable model were established.Suitable planning area of L.japonica in Suiyang County was divided to three regions by using fuzzy method,including suitable zone,sub-suitable zone and unsuitable zone.[Result] The suitable regions were mainly distributed at river road or slop plateau with the altitude below 900 m.Unsuitable areas were mainly distributed in the mountains above 1 200 m.[Conclusion] Low winter temperature,lack of heat conditions and less sunshine are the main factors restricting the further development of L.japonica in Suiyang County.
