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).     

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。     

基于土地发展权的历史文化遗迹所在地区农地保护策略探究

目前我国历史文化遗迹所在地区开发用地失控的原因,从体制方面讲,乃是由于规制手段不够健全、管理体制不够顺畅、城镇化和旅游经济发展进程的阶段性等问题所致;从微观经济层面而言,还在于农民缺乏保护农地的经济诱因、农地转向开发用地收益更高、相关利益集团的势力影响等因素在起作用,故而农地流转成开发用地不可避免。所以应当借鉴海外土地发展权制度,在历史文化遗迹所在地区内落实土地发展权的补偿机制,对开发用地实行有效的管制。具体来说,应当从法律上明确土地发展权的地位,将农地保护与当地的经济社会发展有机协调起来,推行土地使用管制,建立完善土地发展权交易机制,同时有效控制农地流转为开发用地的隐性交易行为。

新型旋转减冲装置对桩基局部冲刷防护试验研究

为减轻海上风电单桩基础周围局部冲刷对其结构安全的影响,提出了一种新型旋转减冲装置。在波流水槽中开展物理模型试验,改变波流条件、装置安装高度、安装距离,记录桩周冲刷发展历时,运用激光地形仪扫描冲刷坑形态,分析各工况下冲刷坑形态差异,验证装置不同安装距离、安装高度下的冲刷防护效果,提出了不同安装位置下的防护效率公式。结果表明：新型旋转减冲装置具有较好的冲刷防护效果,本试验工况下,桩周最大冲刷深度可减小44%左右。装置安装距离对冲刷防护效果影响较小,波流作用下的冲刷防护效果受装置安装高度影响显著,冲刷防护效果随装置安装高度的增加而减弱。     

西南地区传统村落区域保护水平评价及影响因素

本文在理论层面构建传统村落保护研究模型,并以西南地区为例,分析宏观视角下传统村落区域保护水平及影响因素。结论显示：① 传统村落保护研究模型涵盖评价体系和影响因素两个子模型。评价体系模型包含从宏观到微观的传统村落时空分布、整体保护水平和单一属性3个层次,其中整体保护水平分为宏观区域和微观社区两个亚层,保存率和分布密度是评价区域保护水平的简易方法;影响因素模型包含基于时间、空间和类型划分的两类基本分析模型。② 西南地区传统村落区域保护水平呈现显著空间分异,在行政区划边界地区形成5个热点集聚区,丽江市传统村落保存率最高,黔东南州分布密度最高。③ 影响西南地区传统村落宏观保护水平的地理区位因素为海拔、水系、中心城市和交通干道。经济社会因素中,非遗规模是最重要的影响因素,人口密度、经济发展、交通建设、交通流动和非遗规模的相关系数存在显著空间分异,城镇化率、产业结构对于区域保护水平无显著影响。本文是对传统村落保护理论体系由个案向整体、由微观向宏观、由零散向系统、由单一向多元方法的推进,具有重要理论和实践价值。
