摘要
传统的空间推算方法对空间的均质性要求比较高,然而在洪涝灾害中,空间的均质性很难满足。该文将分层非均值地表推断方法(MSN)用于洪涝灾害损失现场调查,建立基于MSN的洪涝灾害现场调查推算模型,并用2013年黑龙江省汛期洪涝灾害验证本模型,总体推算误差控制在15%以内,较好的反应了整个灾区的受损情况。
Traditional spatial calculation method needs homogeneity,but homogeneity usually cannot be satisfied in flood disaster. We use Spatial Means of Surfaces with Stratified Nonhomogeneity method to build A Flood Field Investigation Caculating Method. At last,2013 Heilongjiang Provence foold disater is uesed to verify the model; the error is under 15% which can indicate loss of the whole disaster area.
