| 摘 要： | 基于兰州市以及附近四周其他地区气象站30 a(1981~2010年)的气候资料和154个站点的降水资料,利用地理信息系统(GIS)技术对区域内降水、气温等进行了数据细网格化分析。结合百合田间观测气象和产量资料,采用逐步回归、宏观地理因子模拟与小地形订正等方法,建立了兰州市百合种植区划指标空间分析模型,区划结论与实际种植基本相符,GIS技术制作的区划图结合水平和垂直种植区划辅助参照表,直观详细地展现了百合适生种植区的地理分布及特征,从而减少了种植的盲目性。

| Abstract: | Based on the climate data of 4 meteorological observation stations in Lanzhou and other meteorological observation stations nearby from 1981 to 2010,and the precipitation data of 154 stations,the data gridding analysis of precipitation and temperature were completed by using the technique of GIS.Combined with the field observations and yield data of lily,the planting division indices spa-tial analysis model for lily was established by using methods of stepwise regression,macroscopic geographic factors simulation,and small topography correction.It was found that the model conclusion accorded with the actual planting effect.Division map made by the technique of GIS and the horizontal and vertical planting division reference tables displayed intuitively the geographical distribution and characteristics of suitable planting area for lily in detail,which reduced the blindness of planting lily in Lanzhou. |
