江汉平原土地资源诅咒效应研究

将资源诅咒的研究领域由传统的矿产资源转向土地资源研究问题域,以近10a江汉平原18个县(市)的统计数据为依据,运用诅咒系数对其进行资源诅咒的实证分析。结果显示,近年来发展滞后的荆州市所辖的监利县、江陵县以及其他7个县市的土地资源诅咒系数大于1,确实存在资源诅咒现象,且江陵县与监利县还属于严重诅咒区。通过对选取指标作进一步的计算分析,得出导致其产生资源诅咒的原因主要为:以土地资源为依托的农业没有得到高效发展,而受到发展观念与投入等束缚,其二、三产业发展同样滞后。根据影响资源诅咒地区产业发展的具体因素,有针对性地给出化解土地资源诅咒的对策建议,为今后资源诅咒地区打破诅咒束缚,持续快速发展指明方向。     

水资源量与城市人口规模

城市发展与水资源息息相关。为保证城市规模的合理性,应综合考虑城市的水资源储量。通过城市水资源量估算城市人口规模的方法,以广西钦州水源工程为例,从钦州现有的几个水资源量分析钦州城市可能达到的人口规模,说明城市水资源是影响城市发展规模的主要因素之一。     

Testing The Pearl Hypothesis: Natural resources and trust

Do natural resources reduce social trust? This paper reviews the literature on natural resources and on trust. The existing theoretical and empirical literature suggests that natural resources can reduce trust through several indirect mechanisms. Notably, studies show that natural resources lead to institutional degradation, corruption, inequality, and civil war, all of which have been associated with reduced trust. In addition, game theoretical work on windfall gains suggests that there may be direct effect of natural resources on trust. This paper tests empirically whether there is a direct effect of natural resources on trust (The Pearl Hypothesis), using cross-country data. The results indicate that no such direct effect exists, but we find a significant effect on trust of intermediate variables affected by natural resources, such as institutions, corruption, inequality and/or civil war. Importantly, the relationship between corruption and trust turns out to be non-linear, indicating that the effect of natural resources on trust depends on the initial corruption level of a country. In highly corrupt societies, institutional improvements that reduce corruption may also undermine trust, which poses difficult challenges for anti-corruption policy.     

System Dynamics to Sustainable Water Resources Management in the Eastern Snake Plain Aquifer Under Water Supply Uncertainty1

Abstract: Water supply uncertainty continues to threaten the reliability of regional water resources in the western United States. Climate variability and water dispute potentials induce water managers to develop proactive adaptive management strategies to mitigate future hydroclimate impacts. The Eastern Snake Plain Aquifer in the state of Idaho is also facing these challenges in the sense that population growth and economic development strongly depend on reliable water resources from underground storage. Drought and subsequent water conflict often drive scientific research and political agendas because water resources availability and aquifer management for a sustainable rural economy are of great interest. In this study, a system dynamics approach is applied to address dynamically complex problems with management of the aquifer and associated surface‐water and groundwater interactions. Recharge and discharge dynamics within the aquifer system are coded in an environmental modeling framework to identify long‐term behavior of aquifer responses to uncertain future hydrological variability. The research shows that the system dynamics approach is a promising modeling tool to develop sustainable water resources planning and management in a collaborative decision‐making framework and also to provide useful insights and alternative opportunities for operational management, policy support, and participatory strategic planning to mitigate future hydroclimate impacts in human dimensions.

火电燃料消费过程对资源环境的影响评估

我国以化石能源为主要燃料的火电生产导致了严重的资源枯竭和环境污染问题，定量评估火电燃料消费对资源环境的影响是区域可持续发展研究的重要内容。在估算火电燃料燃烧及运输、生产过程中排放的主要大气污染物的基础上，利用成分法计算相应的生态足迹，定量评估火电燃料消费过程对资源环境的影响。结果表明：我国1 kW〖DK〗·h火电的燃料消费过程中排放的CO2、CH4、NOx、SO2、烟尘分别为107 kg、993×10-3 kg、646×10-3 kg、260×10-3 kg、202×10-2 kg；全国火电燃料消费占用的生态足迹由2000年的50 67444万hm2，增加到2007年的123 84208万hm2，年均增长1362％；CO2和NOx的生态足迹平均比重高达836％，是影响资源环境的主要因子，SO2、烟尘与CH4三者合计仅164%，对资源环境的冲击相对较小

基于水量分配方案的抚河流域最小控制需水量研究

鄱阳湖流域水资源丰富，在非汛期尤其是用水高峰期，存在供需水矛盾和河道外用水挤占河道内用水现象。基于水量分配方案，以控制断面为节点，考虑河道外需水，兼顾河道内生态环境需水，系统提出计算流域控制断面最小控制需水量方法。在此基础上，以抚河流域为例，把流域划分为12个控制断面，分别为沙子岭、黎川、南城、洪门、廖坊、石门、廖家湾、娄家村、马圩、焦石、柴埠口和李家渡，各断面的最小控制需水量分别为740、380、2873、1200、4981、261、5085、7168、050、10894、1556 和1030 m3/s。通过水文监测控制流域断面流量，为落实水量分配方案、保护流域水环境和维持河流生态系统健康提供保障。同时，以最小需水量并与实测流量比较，确定各用水区余缺水量，为实施流域非汛期水量调度提供依据
