简介：城市的簇在一个国家是工业和都市化的高水平的期望的产品，以及是在全球竞争的参予的基本单位。关于中国，城市的簇为增加中国都市化过程被认为是主导的形成。然而，迄今为止没有技术的重合、有效、可信的方法学的系统和集合识别中国城市的簇。这研究调查地理信息技术支持提供中国城市的簇的分发的更好的理解的一个计算机化的鉴定方法的潜力。鉴定方法在ArcInfo宏语言编程的帮助下基于一个地理信息数据库，一个数字举起模型，和社会经济的数据被执行。在方法，初步的边界根据交通可接近性被识别，并且最后的鉴定从在rasterized的帮助下在一个区域限制城市数字，人口，和GDP被完成社会经济的数据集。结果证明方法识别九中国城市的簇，即，珀尔河三角洲，更低的长江山谷，Beijing-Tianjin-Hebei区域，东北中国平原，中间的长江山谷，华中平原，西方的台湾海峡，Guanzhong和Chengdu重庆城市的簇。这研究代表包含中国城市的簇的计算机化的鉴定的第一研究。而且与另外的相关研究相比，研究途径，联合交通可接近性和社会经济的特征，被显示是识别城市的簇的一个不同、有效、可靠的方法。

简介：题目：区域降雨频率分析中的质量和数量不确定性分析目的：通过引进NUSAP方法量化区域降雨频率分析不确定性来源中质量方面的不确定性，并结合数量方面的不确定性，分析这些不确定性对降雨频率分析的影响，为水资源风险决策和水利工程设计等提供更好的指导。　　创新点：总结区域降雨频率分析中的不确定性来源，并在区域频率分析中引进NUSAP方法用以量化其质量不确定性，针对区域频率分析提出Pedigree矩阵。　　方法：1.选取区域频率分析中三个主要不确定性来源，即降雨测量不确定性、水文分区不确定性和分布线型的不确定性；2.提出针对区域频率分析的评价依据Pedigree矩阵，量化区域频率分析中的质量不确定性；3.将质量和数量两类不确定性结合在不确定性诊断图中，综合评估区域频率分析中的质量不确定和数量不确定性。　　结论：NUSAP方法可以有效地量化区域降雨频率分析中的质量不确定性，并通过不确定性诊断图将质量不确定和数量不确定性很好地结合起来，为水资源风险决策和水利工程设计等提供了直观的方案。

简介：推迟的沉积的遥感上的量的申请是遥感学习的设计申请的一个重要方面。在这份报纸，厦门海湾被选择为学习区域。遥感数据的十一个不同阶段被选择建立一个量的遥感模型由使用遥感图象和伪同步的测量沉积数据印射推迟的沉积。基于开发的实验统计是在即时推迟的沉积集中和集中以及变换在表面层之间建模的平均tidally的推迟的沉积之间的变换模型推迟的沉积集中和平均深度的推迟的沉积集中。在这个基础上，量的应用程序推迟的沉积的遥感上的综合模型被开发。由象多时间的遥感图象一样使用这个模型，平均的多年推迟了厦门海湾的沉积集中被预言。在模型预言和多年平均的观察数据表演之间的比较象附近的地点的集中差别一样推迟了学习地点的沉积集中能被遥感模型很好与21.61%的错误率或更少预言，它能满足隧道免职计算的设计要求。
