摘 要:
为了揭示热量资源的空间分布特征,满足设施农牧业工程、工农业基地工程的建设以及开发利用热量资源各用户的需求,利用GIS工作平台,采用半经验半理论气候资源回归模拟方法,将呼伦贝尔市热量资源推算到3″×3″小网格上,建立的50个表征热量资源空间分布模型,44个通过了极显著性检验,6个通过了显著性检验;有92%的模型回代检验和90%的模型模拟检验的平均相对误差均在-5%~5%;实现了热量资源快速、准确的查算;在此基础上分析了热量资源的空间分布规律,为该地区充分合理利用热量资源提供科学依据。[著者文摘]

Abstract:
In order to reveal the spatial distribution of energy resources and assure the needs of users for energy resources in establishment agricultural engineering, industrial and agricultural base construction and development process of energy resources, heat resources of Hulun Buir city was calculated to the projection of 3″×3″ mini grid by GIS software and the semi-empirical and semi-theoretical climate simulation methods. 50 token spatial distribution models of heat resources were established, 44 of which were at great significant level and others at significant level. The average relative errors of both 92% model-return test and 90% model-model test were between -5% and 5%. Heat resources can be calculated and investigated promptly and accurately in this way. On these bases, the rules of the spatial distribution of energy resources were analyzed in order to provide a scientific basis in case that heat resources can be utilized adequately and rationally in the region.[著者文摘]
