金塔柽柳在甘肃沙区的气候适宜性分析

Analysis of Climate Suitability for Tamarix jintaenia Planting in Desert Areas of Gansu Province

选取年均降雨量、年均蒸发量、年均气温、年日照时数、极端高温、极端低温、相对湿度和≥0℃积温等8个气候因子作为金塔柽柳在甘肃沙区的气候适宜性栽培条件,以金塔县的金塔柽柳为固定样本,以甘肃沙区的景泰县、民勤县等15个县市区的气候资料为依据,用模糊相似优先比法进行分析,将15个县市区划分成4类金塔柽柳的适宜性区域:适宜区、较适宜区、基本适宜区、不适宜区。

Eight factors including average annual rainfall, average evaporation capacity, average temperature, annual sunshine hours,extreme high temperature,extreme low temperature, relative humidity and ≥0℃ accumulated temperature were selected as climate suitability cultivation condition in Gansu desert region. Taking Tamarix jintaenia in Jinta County as the fixed sample, climatic data of 15 counties and urban districts, such as Jingtai and Minqin County in Gansu desert region, were analyzed by vague comparative method of similarity priority. Fifteen counties and urban districts were divided into 4 kinds of suitable areas： suitable area,fairly suitable area,almost suitable area and unsuitable area.
