为贯彻党中央、国务院领导同志关于地质灾害防治工作的指示和2010年全国汛期地质灾害防治工作视频会议精神,进一步加强和做好汛期地质灾害防治工作,部研究决定,开展汛期地质灾害防治工作检查。检查分两个层面,一是从5月至6月,由国土资源部领导带队,联合交通运输部、铁道部、住房城乡建设部、水利部、中国地震局、中国气象局、电监会、安全监管总局、国家防总、民政部和国务院三峡办,对浙江、福建、江西、湖北、湖南、广东、广西、重庆、四川、贵州、云南、陕西、甘肃、青海等14省(区、市)的汛期地质灾害防治工作情况进行检查;二是其他各省(区、市)国土资源厅(局)会同本省(区、市)相关部门组织检查。现就有关事项通知如下: 相似文献

针对当下全球的水域环境监测中水体提取不完整、与周围地物区分错误等问题,以山东潍河为研究对象,提出了一种改进分水岭分割方法。首先提取目标水体的光谱信息分量作为前景图,然后将膨胀后的水体对象作为背景图,利用前景图与背景图叠加生成标记图,最后利用标记图通过分水岭变换对原图像进行分割以实现水体信息的自动提取。本文将试验结果与OpenCV中手动标记种子点的分水岭算法、基于Canny边缘的分水岭算法、结合形态滤波和标记的分水岭分割方法结果进行了对比。结果表明,本文算法比用种子点手动标记的方法更加自动化,提取的水体更加完整准确;相比于Canny边缘方法又避免了过度分割;比结合形态滤波标记的方法也更加完整准确,目标水体明显,对于水体提取是一种自动化的有效方法。 相似文献

Use of Information Technology for Community Empowerment: Transforming Geographic Information Systems into Community Information Systems 总被引:4,自引:0,他引:4
Rhina Ghose 《Transactions in GIS》2001,5(2):141-163
GIS has emerged as an elitist, anti-democratic technology by virtue of its technological complexity and cost. The question of democratizing this technology has been addressed in the GIS and Society literature. This paper addresses the thorny issue of uneven access to GIS and the associated social power it confers. Following the principle that effective access to information leads to better government as well as to community empowerment, this paper explores the issues of providing equitable access to GIS at the grass-roots level. The paper discusses a university/community partnership with the distressed, inner city neighborhood of Metcalfe Park in Milwaukee, Wisconsin. In this project, the members of an inner-city neighborhood organization were given training in GIS for accessing public information, creating new databases from their own surveys, and analyzing these databases, with the purpose of making them able and active adjuncts to the conduct of city management and the formation of public policy. The paper evaluates the successes and failures of the project. It also explores the nature of GIS usage in this resource poor community organization between 1993–2000. 相似文献

Optimization of land use structure consists of economic and social and ecological optimization. Applying the minds of system engineering and principles of ecology, this paper presents such thoughts: the optimal forest-coverage rate calculated according to the reality of a district is set as main standard of ecological rationality in the district; through considering the value of ecosystem services of the land with GREEN equivalent (mainly cultivated land and grassland) and based on the rule, GREEN equivalent, this paper introduces the area conversion between woodland and cultivated land, also between woodland and grassland; this paper establishes a multi-dimension controlling model of optimization of land use structure. In addition, a multi-objective linear programming model for optimization of land use structure is designed. In the end, this paper tests and verifies this theory of ecological optimization, taking Qionghai city in Hainan Province as an example. 相似文献
