| 摘 要： | 在ArcGIS支持下,基于数字高程模型(DEM),采用聚焦分析和相关分析方法,对1997-2006年黑龙江省旬平均气温与地面高程的相关性进行定量分析.结果表明,旬平均气温与高程有较高的相关性,与高程值value及50 km左右邻域内高程均值mean的函数相关系数较大,但各旬内的相关程度不同.作物生长期各旬平均气温与地面高程的相关系数较大,最大相关系数在-0.4889～-0.8209,平均为-0.6905.这对农业气候资源研究中旬平均气温精确插值具有重要意义.

| Abstract: | Supported by ArcGIS software,adopting focal analysis and correlation analysis methods,using 10-day air temperature,based on digital elevation model(DEM),the quantitative relativity between average 10-day air temperature from 1997 to 2006 and ground elevation in Heilongjiang Province has been worked out.The results show that there are higher relativity between average 10-day air temperature and ground elevation but different correlation coefficients in each 10-day period,representing larger correlation coeff... |
