淄川太河矿泉水保护与开发利用现状及产业发展

淄川太河矿泉水水源地位于淄博市淄川东南部山区的太河镇境内,是淄博市主要水源地。该水源地矿泉水类型以含锶型弱碱性水为主,也有少量较奇缺的锂锶复合型弱碱性水,资源丰富,品质优良,是一个不可多得的矿泉水聚集区。但由于管理不规范等原因,淄川矿泉水产业面临市场竞争力弱,开发秩序混乱、可持续发展能力不强等问题。开发利用过程中应做到:坚持保护为先确保矿泉水资源可持续开发、实施综合整治规范矿泉水产业秩序,坚持科学开发努力实现资源效益最大化。     

Using a Bayesian estimator to combine information from a cluster analysis and remote sensing data to estimate high-resolution data for agricultural production in Germany

In Germany, a county-resolution data set that consists of 35 land-use and animal-stock categories has been used extensively to assess the impact of agriculture on the environment. However, because such environmental effects as emission or nutrient surplus depend on the location, even a county resolution might produce misleading results. The aim of this article is to propose a Bayesian approach which combines two sorts of information, with one being treated as defining the prior and the other the data to form a posterior, used to estimate a data set at a municipality resolution. We define the joint prior density function based on (i) remote sensing data, thus accounting for differences in county data and missing data at the municipality level, and (ii) the results of a cluster analysis that was previously applied to the micro-census, whereas the data are defined by official statistics at the county level. This approach results in a fairly accurate data set at the municipality level. The results, using the proposed method, are validated by the national research data centre by comparing the estimates to actual observations. The test statistics presented here demonstrate that the proposed approach adequately estimates the production activities.

Multilateralism in the Straits of Malacca and Singapore

This paper analyzes International Maritime Organization (IMO) involvement in maritime cooperation regime in the Straits of Malacca and Singapore through multilateralism. It begins by introducing the maritime cooperation regime prior to 2001, which was mainly trilateral in nature through Tripartite Technical Expert Group on the Safety of Navigation (TTEG). Although TTEG managed to increase the level of safety of navigation in the Straits of Malacca and Singapore through the implementation of the Traffic Separation Scheme (TSS) in 1981 and Mandatory Ship Reporting System (STRAITREP) in 1998, such cooperation was beset by financial strain and conflict of interests. Subsequently, there was a change in the cooperation regime after 9/11 incident. This paper identifies that the change was contributed by the IMO through a methodology called multilateralism. Three important principles were adopted by IMO in implementing multilateralism in the Straits of Malacca and Singapore, namely generalized principles of conduct (respect for sovereignty and compliance with burden sharing principle under Article 43 of UNCLOS 1982), diffuse reciprocity, and indivisibility. This paper concludes that multilateralism by IMO has transformed trilateral cooperation into multilateral cooperation in the Straits of Malacca, combining state actors (littoral states and user states) and non-state actors (non-governmental organizations and international shipping industries).     

陕南地区膨胀土滑坡形成机理及防治措施

以陕西省南部汉台区地质灾害详细调查项目为依托,通过对汉王镇红星村三、四组滑坡的勘查,发现汉台地区膨胀土滑坡的形成与区内自然地理、地形地貌、地层岩性、降水、地表水和人类工程活动密切相关。研究提出以排水工程、支挡工程和地基换填为主的综合防治措施,为汉台区地方政府地质灾害的防治、减灾工作提供依据,在陕南地区具有一定的推广意义。

基于模糊综合评判和GIS技术的矿山地质环境影响评价

蒲白矿产资源集中开采区分布于渭北黑腰带地区的蒲城和白水县,煤炭、石灰岩、铝土矿和粘土等多种矿产的持续开发,产生了各类的矿山地质环境问题,其中煤矿采空区塌陷及裂缝最为突出。选取了地形相对高差、岩土体特征、开采方式、有效深厚比、采空区面积比、矿山地质灾害发育密度、地下水位、压占破坏土地资源等11个指标作为评价因子,构建了矿山地质环境影响评价指标体系。采用模糊综合评判法对研究区矿山地质环境影响进行评价,并结合GIS空间分析技术划分为矿山地质环境影响严重区12个,较严重区4个,较轻区2个。评价结果与实际调查情况较为相近,较客观的反映了采矿活动对矿山地质环境的影响,并结合区内实际提出了矿山地质环境恢复治理措施建议,为矿山地质环境保护与恢复治理提供了依据。     

新郑矿区地热资源潜能分析与保护建议

基于新郑矿区以平均每年0.0813×108m3的涌水量向地表排放热水,造成的地热资源损失和污染环境的现实,在分析地温地质条件基础上,利用热储资源量公式、卡明斯基公式和弹性储存量公式,分别计算了矿山开采前和开采后不同类型地热资源量,并对当前矿区地热潜能进行了评估。在此基础上,提出了选择煤层底板加固技术,保持岩溶裂隙水一定的水位、减少地下水排放和利用识别模型,选择适宜区段作为地热资源开采区,以调减矿山日常的排水量,尽可能维持渗流场基本不变,进而提高热储的潜能,实现节能减排,达到保护与利用地热资源的效果的建议。
