响应矩阵技术在唐马试验场地下水管理中的应用     

王恩志 《地球科学与环境学报》1989,(2)

响应矩阵技术是解决地下水管理问题的方法之一,它是通过表征系统结构特征的单位脉冲响应函数来求得由抽水产生的水位分布,并以此作为线性规划的约束条件建立地下水系统的水动力管理模型。本文造过对唐马试验场水文地质条件的分析,建立数学模型并将其分解和离散,对渗流区内各井点作用一单位脉冲来形成响应矩阵,建立水动力管理模型和水位预报方程,对本区未来地下水开采进行优化决策。  相似文献

The Potential of Fuzzy Multi-objective Model for Rainfall Forecasting from Typhoons   总被引：1，自引：0，他引：1

This study applies the fuzzy multi-objective approach to forecast short-term (around 24 h) typhoon rainfall, which can be implemented without much background meteorological knowledge. The physical characteristics of 40 typhoons, including route, central pressure, central velocity and cyclonic radius, were used as the data set. The fuzzy multi-objective method mined information from the database to forecast both the depth and pattern of rainfall, which were then combined to estimate a cumulative rainfall curve. The results of calibration with reference to 40 historical typhoon events and the results of validation using another five typhoon events indicate that the proposed model has the potential to forecast short-term cumulative rainfall curves if more variables can be included and more historical typhoon events can be collected to enlarge the database.  相似文献

Typhoon disaster is one of the most influentialnatural disasters. The strong storm surge of Bangla-desh cyclone, which happened in November 1970,resulted in 300000 deaths. Asia and the western Pa-cific can be regarded as an area where is affected mostseverely by the disasters of tropical storms[1]. Themost important thing is to improve the accuracy oftyphoon tracks prediction internationally. Lande-sea,C.[2] pointed out that for a successful forecast oftropic cyclone (TC) tracks, it is not …  相似文献

基于决策树分类的地表覆盖遥感信息提取     

翁中银  何政伟  于欢 《地理空间信息》2012,(2):110-112

地处西南的渝北地区地表覆盖类型复杂、土地利用多元化,仅依赖于光谱特征的传统遥感信息提取方法难以获得较高的分类精度。利用决策树分类技术对渝北地区的TM遥感影像进行分类,除光谱信息外还结合地质、NDVI、PCI等多源数据进行实验。结果表明,总精度和Kappa系数分别为88.42%和0.854 7,较传统的监督分类和仅依赖于光谱特征的决策树分类方法有较大提高,这也表明基于多源数据的决策树分类技术对地表覆盖复杂地区的遥感影像分类比较适用,是遥感信息提取的一种有效手段。  相似文献

陈志千  吴旋 《测绘与空间地理信息》2012,35(4):217-220

在计算机数字制图过程中,地图注记的配置直接影响数字地图的效果.针对地图注记配置过程中两个或多个注记之间冲突处理的问题,本文参照格式塔原则,从地图注记的易读性、位置优先性、形状相似性、地物关联性四个格式塔因子出发对地图注记的候选位置进行评价;同时根据多目标决策理论,用进化算法模拟地图注记的自动配置过程,实现了地图注记自动配置的全局优化.  相似文献   

水资源可持续利用规划耦合模型与应用   总被引：8，自引：4，他引：8  

蒋业放  梁季阳 《地理研究》2000,19(1):37-44

介绍了水资源可持续利用规划耦合模型和应用实例。从数学形式上看,它是多目标优化模型,目标函数选用自由度较高并具竞争性的系统状态指标;约束条件应该包括各相关子系统的状态模拟方程,使模拟与优化实现耦合。在研究实例中,选用了GDP和COD排放量指标来表征研究区的经济发展和环境状况,约束条件主要包括水资源系统模拟模型和宏观经济系统扩大再生产—投入产出耦合模型。由于水资源可持续利用规划决策是半结构化的决策问题,开发决策支持系统辅助决策有助于提高决策的科学性和有效性。  相似文献
