把Savitzky-Golayr滤波方法拓展至二维,提出了基于Savitzky-Golay方法的遥感影像融合算法,并通过与HSI变换、PCA变换和小波变换融合等传统融合算法的比较,证明该方法性能最优.分析Savitzky-Golay滤波算子阶数和小波变换尺度对融合影像质量的影响,发现Savitzky-Golay滤波融合过程中Savitzky-Golay滤波算子阶数是决定融合质量的关键因素.算子阶数越高,融合后影像细节信息越丰富,但光谱信息损失也越严重;算子阶数越低,融合后影像光谱信息保持能力越好,但细节信息增强能力变弱.如何根据具体的遥感影像自动确定最佳的算子阶数是下一步要解决的问题.  相似文献   

共建 共保 共享——建设矿村共享矿产资源开发成果新机制的构想     

陈志刚 《国土资源情报》2011,(7):13-20

随着资源的开发,在发展经济的同时也带来了不容忽视的社会问题,因采矿诱发的地质灾害日益突出,矿业经济发展与矿区群众增收致富脱节,引发了矿群矛盾,给社会和谐稳定带来负面影响。资源型经济对资源开发利用的高投入、高消耗、高排放,不仅加剧了能源、资源紧张矛盾,加大了环境压力,也制约了经济发展质量和效益,资源的供给和利用、生态环境的保护和改善与经济健康发展的矛盾日益突出。为此,积极探索加强矿区环境保护、社会稳定、民生改善和社会发展的有效途径与办法,已成为关系矿业地区经济社会发展的一项重要任务。本文从资源开发的矿村共建、矿产资源与生态环境的共保和资源开发成果的共享进行分析,提出矿村共享资源开发成果新机制的构想。  相似文献   

关于盘活废弃国有建设用地的思考——以云南省曲靖市为例     

陈志刚  刘德祥  傅友文 《国土资源情报》2010,(4):38-40,45

西南地区的三线军工企业是我国20世纪60-70年代的特殊产物，随着市场经济的发展，企业搬迁，形成大量荒废闲置建设用地。本文根据在云南省曲靖市的调研情况，按照国土资源部党组“积极主动服务、严格规范管理”的要求，通过分析其盘活的必要性和可能性，提出了参照城乡建设用地增减挂钩的原则，通过对其确权并复垦来盘活国有废弃建设用地的思路，提出了盘活的原则、方法和保障措施。  相似文献   

浅析新型城镇化的土地支撑     

伍美茹  陈志刚 《国土资源情报》2014,(11):37-40

新型城镇化要以人为本,是推进以人为核心的城镇化,提高城镇人口素质和居民生活质量,要把促进有能力在城镇稳定就业和生活的常住人口有序实现市民化作为首要任务。新型城镇化需要土地支撑,要解决人地失调的突出问题,要把实现人地和谐作为主要目标,坚持耕地保护与节约集约用地的基本国策,发挥规划的龙头作用和计划的管控作用,有序推进土地制度改革。  相似文献

地震勘探区内表层及近地表结构的地球物理特征，往往取决于相应的地质体结构的变化．研究不同表层及近地表地质体的地质特征和地球物理特征，对地震勘探中静校正方法的确定以及静校正量的求取至关重要．准噶尔盆地就其表层地质结构可分为山前冲积扇、戈壁、农田、沙漠等类型，不同类型的地质结构体具有各自独特的地球物理特征。  相似文献   

Dynamic stress concentration and scattering of SH-wave by interface elliptic cylindrical cavity     

陈志刚  刘殿魁  杨在林 《地震工程与工程振动(英文版)》2003,2(2):299-306

In this paper, the dynamic stress concentration and scattering of SH-waves by bi-naterial structures that possess an interface elliptic cavity are investigated. First, by using the complex function method, the Green‘s function is constructed. This yields the solution of the displacement field for an elastic half space with a semi-elliptic canyon impacted by an anti-plane harmonic line source loading on the horizontal surface. Then, the problem is divided into an upper and lower half space along the horizontal interface, regarded as a harmony model. In order to satisfythe integral continuity condition,the unknown anti-plane forces are applied to the interface. The integral equations with unknown forces can be established through the continuity condition, and after transformation, the algebraic equations are solved numerically. Finally, the distribution of the dynamic stress concentration factor (DSCF) around the elliptic cavity is given and the effect of different parameters on DSCF is discussed.  相似文献

Study on regional carbon emission is one of the hot topics under the background of global climate change and low-carbon economic development, and also help to establish different low-carbon strategies for different regions. On the basis of energy consumption and land use data of different regions in China from 1999 to 2008, this paper established carbon emission and carbon footprint models based on total energy consumption, and calculated the amount of carbon emissions and carbon footprint in different regions of China from 1999 to 2008. The author also analyzed carbon emission density and per unit area carbon footprint for each region. Finally, advices for decreasing carbon footprint were put forward. The main conclusions are as follows: (1) Carbon emissions from total energy consumption increased 129% from 1999 to 2008 in China, but its spatial distribution pattern among different regions just slightly changed, the sorting of carbon emission amount was: Eastern China > Northern China > Central and Southern China > Southwest China > Northwest China. (2) The sorting of carbon emission density was: Eastern China > Northeast China > Central and Southern China > Northern China > Southwest China > Northwest China from 1999 to 2003, but from 2004 Central and Southern China began to have higher carbon emission density than Northeast China, the order of other regions did not change. (3) Carbon footprint increased significantly since the rapid increasing of carbon emissions and less increasing area of pro-ductive land in different regions of China from 1999 to 2008. Northern China had the largest carbon footprint, and Northwest China, Eastern China, Northern China, Central and Southern China followed in turn, while Southwest China presented the lowest area of carbon footprint and the highest percentage of carbon absorption. (4) Mainly influenced by regional land area, Northern China presented the highest per unit area carbon footprint and followed by Eastern China, and Northeast China; Central and Southern China, and Northwest China had a similar medium per unit area carbon footprint; Southwest China always had the lowest per unit area carbon footprint. (5) China faced great ecological pressure brought by carbon emission. Some measures should be taken both from reducing carbon emission and increasing carbon absorption.  相似文献
