流域尺度土地利用调蓄视角的雨洪管理探析

发达国家雨洪管理焦点历经管网设计、不透水面阈值控制、低影响开发及土地利用管理等过程,呈现"多尺度多视角衔接"趋势。本文聚焦太湖流域土地利用调蓄功能变化机制及管理应用,揭示了1985-2015年来建设占用耕地是调蓄功能降低的主要原因;发现基于小流域的调蓄功能变化与建设用地强度整体低关联,但局部高相关,高相关的地区位于大城市或某些乡镇周边的建设增长热区,而这些热区的建设用地与调蓄空间规模较大且接触机会更多,是开发之前调蓄空间保护、开发控制以及开发之后综合管理等3个土地利用调蓄目标因子协调不当的结果;最后提出流域尺度土地利用调蓄视角的雨洪管理"345"模式,即以3个目标因子和5类控制要素为基础,实施土地利用调蓄创建、防御、拓展与保护等4类差别化战略模式,从更大尺度认识老城区和新区的雨洪关联,拓展海绵城市建设的本土认知和视野。     

微机在土工试验中的应用

采用质量管理体系是企业的一项战略决策,它亦是企业实施管理标准化、规范化的最佳途径。如何将其融入微机化管理,构建一个集管理、专业及系统分析软件为一体的信息化模式,以提高试验模拟与实际工程相关参数的准确度,在当今信息及网络高速发达的市场经济时代,是一个值得关注和研究的课题。     

基于“数字城市”地理空间框架的国土资源档案管理系统的设计与实现

INTEGRATED RISK ASSESSMENT OF MAJOR METEOROLOGICAL DISASTERS WITH PAPRIKA PEPPER IN HAINAN PROVINCE

Paprika pepper, as one of the main vegetable crops, is originated in the tropics and now widely planted in the world for its dietary therapy and medicinal functions. For its typical physiological properties referring to low tolerances to flood, drought and cold, paprika pepper often suffers from one or several disasters during its growing period, especially under tropical climate. Paprika pepper in Hainan, as a typical region of tropical climate in China, sustains flood, chilling and drought disaster risks induced by varied weather systems. This study was to develop and employ appropriate indices to assess hazard, sensitivity, vulnerability and prevention capability for major disasters during paprika pepper growth period, using long-term meteorological data from 1998 to 2011, actual disasters record from 1999 to 2011, production and socioeconomic statistics from 2002 to 2011 at 18 weather stations. Based on the Analytic Hierarchy Process and Entropy method, the combined weight was given to each disaster factor, thus an integrated disaster risk assessment model was developed and applied at regional level. High flood hazard mainly occurred in eastern Hainan, high chilling hazard in north and central mountain areas, and high drought hazard in the western part of Hainan. Drought and chilling sensitivity had a similar spatial distribution which decreased from central to coastal regions while flood sensitivity was the opposite. High vulnerability of the disasters mainly occurred in central regions, similar to low prevention capability. Eastern Hainan suffered from high integrated damage risk. The predicted damage occurrence showed a good agreement with the occurrence of actual disasters. We concluded that an integrated damage risk assessment model could provide a new tool to assess major meteorological disasters and help farmers and policy makers to alleviate the risks of major meteorological disasters for paprika pepper, which seems also suitable for other crops.

A voluntary reduction in the commercial catch of rock lobster (Jasus edwardsii) in a New Zealand fishery

We describe the development and application of a management procedure (decision rule) that resulted in a voluntary reduction in the commercial catch of spiny rock lobster (Jasus edwardsii) in the lower east coast of North Island of New Zealand. The management procedure was developed from an accepted assessment of the CRA 4 (Wellington‐Hawke's Bay) fishery, which used an integrated length‐based assessment model fitted to commercial fishery catch‐per‐unit‐effort (CPUE) biomass indices, commercial length‐frequency data, and tag‐recapture data. The assessment model had been Bayesian, and used the joint posterior distribution of parameters to predict the effect of 384 alternative harvest control rules on the future size of the CRA 4 stock. The harvest control rules all used CPUE as their input, and generated annual changes in catch, which were then simulated by the population dynamics of the operating model. Uncertainty was added to evaluations through observation error, added to the simulated CPUE observations, and stochastic serial auto‐correlation variation in recruitment. We describe how this management procedure was used to effect a voluntary reduction in catch to address the problem of a rapidly declining population.     

关于海岸带开发“稳健管理模型”的初步设想

海岸带可持续发展需要具有数据分析和决策的双重功能的计算机“稳健管理模型”。在技术上 ,该管理模型可利用地理信息系统和数据库技术 ,实现法律文件、区域性社会和经济发展规划、海岸带自然环境数据、以及土地利用现状资料的贮存和分析。然后通过一个决策软件 ,将有关资料转化为可持续发展的若干条最大容量规则 ;该软件以海岸带开发项目所需的必要条件为输入参数 ,通过内部一致性检验确定这些条件是否符合可持续发展规则 ,从而对待开发项目作出批准与否的管理决策。随着计算机技术的发展 ,开发这样一个稳健管理模型的时机已经成熟。     

CITES-listings,EU eel trade bans and the increase of export of tropical eels out of Indonesia

Following the decision in 2007 by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to include European eel Anguilla anguilla on its Appendix II, and the 2010 ban of all eel exports by EU member states, a shift has occurred to tropical Asian eel species to meet the demand from East Asia. Here the focus is on the role Indonesia played in fulfilling this demand using official export figures, reports in the Indonesian media and government documents. Despite Indonesia first putting in place restrictions on the export of eel in 1974 the export has increased exponentially over the last 25 years. Prior to the EU ban it exported ~1.4 million kg/year. With the infrastructure in place, and close trade links to East Asia, and helped by government encouragement, Indonesia was in an excellent position to step in where the EU posed restrictions. Exports increased to 3.2 million kg/year (2007–2009), to 4.0 million kg/year (2010–2012), and to 6.1 million kg (2013). The interest in eel trade in Indonesia increased in parallel with the exports. From 2010 onwards the searches for the Indonesian equivalent of eel (“ikan sidat”) became frequent enough for it to be picked up by Google Trends. Indonesia is home to five species of eel, and while it is unclear in what quantities each is traded, Indonesian media reports suggest that the majority comprises A. bicolar and A. marmorata. More stringent management schemes, possibly including CITES-listing, and better monitoring are needed to ensure that international trade is not an impediment to the conservation of tropical eels.
