分布式雷达目标时序InSAR技术是目前InSAR形变监测领域的主流方向,其中同质样本选取是该技术的基础,其估计精度直接影响SAR影像分辨率与后续参数解算精度.本文在追踪最新研究进展之上,系统回顾了当今统计同质选点算法的优缺点.在参数与非参数两类统计方法的应用中,采用蒙特卡罗方法和真实数据验证定量比较算法差异以及适用场景.根据之前的研究结论,提出一种改进的最优参数统计同质样本选择方法.最后,论文介绍...
水资源费视角下工业水价的结构性调整是实现工业节水和建设节水型社会的重要手段,其调整思路有二:一是改变水资源费标准,二是调整水资源费占终端水价的比重。研究表明,一方面,工业用水中的地下水和地表水存在显著的替代效应,地下水和地表水水资源费对地表水需求的影响较地下水需求更大;另一方面,以地表水水资源费和地下水水资源费代替终端水价中的水资源费所构造起来的水价结构放大了水资源费对工业用水需求的影响,其中,通...
