基于界限温度的格尔木枸杞种植气候区划

Climatic Zoning of Wolfberry Planting Based on Boundary Temperature Golmud

利用以格尔木市1981~2015年气象站逐日气温、降水资料、积温(0、3、5、10℃)等数据。格尔木市气象台站气候资料与经度、纬度、海拔建立回归模型,基于地理信息系统,实现了格尔木市枸杞的精细化气候区划。结果显示:格尔木盆区枸杞平均生育期大约在142-172d左右;考虑枸杞自身的发育期水份利用的特性,格尔木属于灌溉农业,蒸发量是降水量的53倍,故自然降水对枸杞发育期影响不大。在具有灌溉条件的乌图美仁乡、小灶火、河西农场大格勒乡一带是枸杞种植最为适宜的区域,是格尔木地区枸杞种植的主要区域,而格尔木地区西北部是南陵丘自然区、甘森、涩北气田,虽气候条件适宜种植枸杞,因自然资源开发等原因,枸杞种植较少。

The data of daily temperature,precipitation data,accumulated temperature（0,3,5,10℃）and so on were used in the weather station of Golmud from 1981 to 2015. A regression model of climate data,longitude,Latitude and altitude was established at Golmud meteorological station. Based on geographic information system（GIS）,the detailed climatic division of Lycium barbarum was realized. The results showed that the average growth period of Lycium barbarum was about 142 - 172 d. Taking into account the characteristics of water utilization in the development period of Lycium barbarum,Golmud belongs to irrigated agriculture.The evaporation rate is 53 times that of precipitation. It is the most suitable area for Lycium barbarum cultivation in the area of Utunmeren,small kitchen fire and Daguerre Township of Haixi Farm with irrigation conditions. It is the main area for Lycium barbarum cultivation in the area of Golmud,while the area in the northwest of Golmud is the natural area of Nanlingqiu,Gansen and Shibei gas field.
