摘要
文章采用多源多时相高分辨率遥感影像作为数据源,以ArcGIS、Erdas、Envi等遥感地信软件为信息提取平台,对青海省湟水流域的采砂场进行遥感调查分析。结果显示:①采砂场主要分布在湟水流域城市周边,其中,在用采砂场分布较密集,如西宁、湟中、平安附近分布较集中,而停用采砂场分布相对比较均匀;②采砂场共305处,其中长期和临时采砂场占重要比例,达73%,经过平整或绿化的停用采砂场较少,而停用且无整改及整改中的采砂场数量仍较多,是已整改的2倍;③长期采砂场面积规模占所有类型总面积的比重最大,达三分之二,而经过平整或已绿化的规模仅0.75 km2。研究以期对环境监察管理提供技术支撑,为后续的研究和砂场的高效精准管理提供技术方法和科学依据。
The paper investigated and analyzed sand dredging plants in Huangshui River valley of Qinghai province using multitemporal high-resolution remote sensing image with the remote sensing and geographic information software of Arcgis、Erdas and Envi.The results showed that：（1） sand dredging plants distribution was relatively dense and near to the city,such as Xining and Huangzhong.Among all types,operating sand plants distribution were more dense than closed sand plants which distributing uniformly.（2） there was a total of 305 sand dredging plants,and long-term and temporary operating plants occupied 73%,in addition,unrepaired and repairing closed dredging sand plans were two times of closed dredging sand plants that had repaired or planted trees.（3） From the aspect of plants sizes,long-term operating plants were the largest contributor amounting two-thirds,and repaired and planted tree closed plants were just 0.75Km^2.This research could provide a technology support for environmental supervision and management,it also could offer technical method and scientific basis for further research.
