成县农业气候资源分析与区划

Analysis and regionalization of agricultural climate resources in Cheng county

采用统计学原理和电子表格、地理信息系统技术对1981—2015年成县气象和农业气象观测资料及水文资料进行统计分析,同时辅以农业、林业和养殖业等方面的资料,分析甘肃省成县的气候资源、气候变化现状、气象灾害影响程度以及气候对种植业、养殖业的影响。用图文并茂的形式综合分析论证了成县气候资源的开发利用和气象灾害对农林业的影响及应对措施,在此基础上应用热量指标、水分指标和综合指标将成县划分为3个气候大区和2个气候亚区,即ⅠA温暖半湿润粮经作物区、ⅡBa温和湿润粮经林木区、ⅡBb温和湿润农林亚区、ⅡBc温暖温和半干旱农经区、ⅢC温凉湿润林牧区。

Statistical principles,spreadsheets and GIS techniques were used for statistical analysis of meteorological and agrometeoro⁃logical observation data and hydrological data of Cheng county of Gansu province from 1981 to 2015.At the same time,the climate re⁃sources,climate change status,the degree of meteorological disaster and the influence of climate on planting and breeding in Cheng county of Gansu province were analyzed with the data from agriculture,forestry and breeding industry.With illustrated in the form of comprehensive analysis demonstrates the development and utilization of climate resources of Cheng county and the effect of meteorolog⁃ical disasters of agroforestry and countermeasures,based on the application of heat index and water index and comprehensive index will become county was divided into three climatic regions and two climatic subregions,namelyⅠA warm semi-humid zone grain eco⁃nomic crop areas,ⅡBa temperate humid climate grain economic forest area,ⅡBb mild and humid climate agriculture and forestry sub region,ⅡBc warm and mild semi-arid agricultural economy area,ⅢC temperature cool moist forests,pastoral areas.
