摘　　要：茶叶产业是四川省广元市旺苍县脱贫攻坚、经济发展重要的一环.根据高品质茶叶生产对气候、土壤、地形环境因子要求,选取4个气候因子、3个地形因子、1个土壤因子作为生态区划指标,基于旺苍县及其周边共30个气象台站1980-2018年逐日气象数据,结合旺苍县1∶50万地理信息数据和数字化土壤图完成茶叶生产生态适宜性区划.结果表明:旺苍县茶叶生产适宜区、次适宜区、不适宜区面积分别占县域面积30.37%,45.13%及24.50%,适宜区主要集中槽谷地带的白水镇、尚武镇、嘉川镇、东河镇、黄洋镇、普济镇、三江镇、金溪镇、大德乡及槽谷地带以北的檬子乡、英萃镇、正源乡,可利用适宜区生态资源优势,提高茶叶种植水平,提升区域品牌影响力.The development of tea industry is an important part of economic development and poverty alleviation in Wangcang countyofSichuan province.In a study reported herein,ecological suitability zoningfor tea cultivation was made,in which4 climatic factors,3 topographic factors and 1 soil factor were selected as ecological suitabilityindexes according to the requirement of quality tea productionto climate,soil and topography.A precise zoning of ecological suitability for tea cultivation was completed based on the daily meteorological datafrom 1980 to 2018 of 30 meteorologicalstations in Wangcang and its surrounding areas,as well as Wangcang 1∶500000 geographic information data and digital soil map.The results showed that the suitable areas,sub-suitable areas and unsuitable areasfor tea productionaccounted for 33.67%,41.10%and 25.31%,respectively,of the total area of the county.The suitable areaswere mainly distributed in the Baishui town,Shangwu town,Jiachuan town,Donghe town,Huangyang town,Puji town,Sanjiang town,Jinxi town,Jinxi townandDade townshipin the valley regions of the county and inMengzi township,Yingcui town and Zhengyuan township in the north.It is recommended that the advantageous climate,terrain and soil resources in thesuitable areasshouldbe utilized to improve the planting level of tea and enhance its regional brand influence.
