加强矿石资源动态管理,确保矿山持续生产

一个已开采46年的老锡矿山，由于后备矿石资源不足，矿山与选厂的生产矛盾日益突出。为了缓解供需矛盾，同时也为了自己的生存与发展，在矿山生产中加强了矿石资源动态管理，客观地分析保有资源，以市场经济为导向，确定合理的经济品位，盘活存量，充分而合理地利用矿石资源，保证了矿山持续生产。     

地勘单位用人问题管窥

针对某些地勘单位干部选拔及用人过程中存在的任人唯亲等不正之风问题,从“考察失真、关系利益、任用随意、责任层次不清”四个方面进行了根源剖析,并着重在“强化责任意识、严格考察程序、规范领导行为、完善监督机制”等方面提出了整改措施。

Andrew U. Frank’s impact on research in land administration

Andrew U. Frank retired in October 2016 after a scientific career of 38 years with positions in Switzerland, Maine and Austria. One of the main applications that he constantly referred to and that he analysed in detail was land administration. This review article tries to give an overview of Frank’s work in the context of land administration and how he influenced the approach to land administration research. He organized his work mainly in four pillars: technical, legal, organizational and economical aspects. Each of them is discussed in the paper and the influence on international cooperation is shown.     

《巴黎协定》与特朗普政府的履约前景

《巴黎协定》生效标志着全球气候治理进程从达约阶段转向履约阶段。但是,履约阶段并不意味着全球气候风险得到控制,反而面临新的挑战。本文从《巴黎协定》入手,分析了《巴黎协定》自身存在的不足,重点考察了美国的履约意愿,分析了特朗普政府退出《巴黎协定》及其影响,探讨了未来美国的气候立场。研究发现,《巴黎协定》在减排力度、气候资金及遵约条款三方面存在先天不足,导致《巴黎协定》有效性仍取决于缔约方的履约意愿和履约能力。当前美国国内政局演变导致美国联邦政府气候政策出现倒退,有可能对《巴黎协定》缔约方的履约意愿和履约能力产生不良影响。但是,这种不良影响仅仅是短暂的。美国在国际格局中的地位变化以及美国业已成形的低碳转型,共同决定了特朗普气候政策并不会从根本上动摇《巴黎协定》。长期来看,美国对全球领导力的诉求、国内应对气候变化的内在动力以及来自外部的道义压力这三大因素势将促使美国在未来重新回归《巴黎协定》。     

顾及生态安全格局的流域生态保护红线划定及管控研究——以云南杞麓湖流域为例

生态保护红线划定是保障国土空间生态安全的重要举措,对保持生态系统的完整性,实现可持续发展具有重要意义.本文基于生态系统服务功能和生态敏感性对杞麓湖流域进行生态安全格局体系的构建,并开展精细化的生态保护红线划定研究,并进一步结合无人机航拍影像及实地调研成果,构建管控路径.得到结论:(1)水源涵养、水土保持、生物多样性、洪水调蓄重要性评价中的极重要区域叠加得到生态系统服务功能极重要区.者湾河、长沙河、大沙河及沟谷密度较大的山区敏感性最高,坝区整体生态敏感性较高.(2)一级生态保护红线范围包括生态极重要区域、生态极敏感区域及湖泊岸线、水库.二级生态保护红线范围包括环湖生态缓冲区、山区林地生态缓冲区及以河流为主的生态廊道.三级生态保护红线范围为生态协调区,土地覆盖以农田为主.(3)一级生态保护红线范围内的生态极敏感区应采取相关生态修复技术进行生态功能的保护.二级生态保护红线范围以生态保护为重点,保持该区域的生态环境质量.三级生态保护红线范围通过生态修复进行整体优化,提高生态环境承载能力.

Land use mapping from CBERS-2 images with open source tools by applying different classification algorithms

Land cover classification is often based on different characteristics between their classes, but with great homogeneity within each one of them. This cover is obtained through field work or by mean of processing satellite images. Field work involves high costs; therefore, digital image processing techniques have become an important alternative to perform this task. However, in some developing countries and particularly in Casacoima municipality in Venezuela, there is a lack of geographic information systems due to the lack of updated information and high costs in software license acquisition. This research proposes a low cost methodology to develop thematic mapping of local land use and types of coverage in areas with scarce resources. Thematic mapping was developed from CBERS-2 images and spatial information available on the network using open source tools. The supervised classification method per pixel and per region was applied using different classification algorithms and comparing them among themselves. Classification method per pixel was based on Maxver algorithms (maximum likelihood) and Euclidean distance (minimum distance), while per region classification was based on the Bhattacharya algorithm. Satisfactory results were obtained from per region classification, where overall reliability of 83.93% and kappa index of 0.81% were observed. Maxver algorithm showed a reliability value of 73.36% and kappa index 0.69%, while Euclidean distance obtained values of 67.17% and 0.61% for reliability and kappa index, respectively. It was demonstrated that the proposed methodology was very useful in cartographic processing and updating, which in turn serve as a support to develop management plans and land management. Hence, open source tools showed to be an economically viable alternative not only for forestry organizations, but for the general public, allowing them to develop projects in economically depressed and/or environmentally threatened areas.
