安徽省棉花冰雹灾害风险区划研究

雹灾风险区划是雹灾风险研究的重要内容,对制定区域性的雹灾防灾减灾对策具有指导意义。而雹灾风险评价是开展雹灾风险区划的前提和基础。以我国雹灾频发区--安徽省为例,选择其主要经济作物棉花为承灾体,基于区域灾害系统理论和棉花雹灾风险区划数据库,在“E-H-V-R”四维评价基础上,提出了多技术手段和多方法相结合的“3（E、H、V）+1（R）”维的雹灾风险区划方法,编制了安徽省棉花雹灾风险图,将其划分为淮北平原区、江淮平原丘陵区和皖南山区3个一级区,10个二级区和19个三级区,为安徽省棉花雹灾风险管理和防灾减灾工作的开展提供科学依据,同时为其他区域和其他灾害风险区划研究提供方法和技术参考     

基于动态因子分析法的四川省旅游业竞争力实证分析

运用STATA统计分析工具,将动态因子分析法应用到旅游业竞争力研究中,借助该方法从纵向和横向分析四川省旅游业竞争力情况,通过分析,重在了解四川省旅游业的发展变化及在全国的地位,为其今后制定有效的旅游业发展战略提供参考。结果表明：运用动态因子分析评价四川省旅游业竞争力客观可行,结果较切合实际。从横向来看,四川省旅游业竞争力在全国处于上游水平,说明综合实力较强;从纵向来看,2006～2010年四川省旅游业竞争力发生明显变化,主要是由于2008年汶川地震造成的影响。进一步提出四川省应注重从5个方面提升旅游业竞争力,即社会经济环境、旅游接待能力和市场、旅游资源、技术人才和生态环境     

Detailed Ecological Footprint Accounting of Liaoning in 2006

Abstract

Ecological footprint (EF) has received considerable attention as a useful indicator in the context of sustainable development. So far, EF has been used in numerous studies by academies, organizations and government authorities. However, the results of these studies failed to be comparable directly with each other due to imprecise data sets, unmodified accounting methods of pasture and fossil energy, ignored secondary products, undefined process of calculating yield factors and improper biocapacity for biodiversity. In this paper, we elaborated on EF estimating methods from six categories of consumption in order to overcome the limitations above. We adopted precise data and revised methods, calculated EF of some secondary products, introduced weighted factor to calculate yield factors and adjusted biocapacity by an appropriate amount. Meanwhile, we investigated the resource consumption of Liaoning Province in 2006 to assess EF. Its results showed that Liaoning Province overused its natural capital and was in an unsustainable state. We concluded that two specific problems that had arisen in EF assessment and gave some suggestions for Liaoning Province to improve its unsustainable state.     

Evaluation of the Rural Human Settlement in Shandong Province

Abstract

Taking Shandong Province as the research object, this paper uses the principal component analysis method to evaluate the status of the rural human settlement in Shandong Province. It establishes the evaluation index system of the rural residential environment in Shandong Province, including living environment, economy, infrastructure, public service facilities, and ecological environment, in total five comprehensive index, and 20 secondary indexes. Through measurement and sorting of rural human environment development level of Shandong Province in 2010, the 17 cities are divided into-excellent, good, ordinary, poor-four development areas and are analyzed based on the restriction factor in the development of the region.     

Study on Development of the West of Shandong Province Based on Overall Regional Development Planning Pattern

The overall regional development planning pattern has been considered to be a new and effective pattern as for development of provincial economy. The article analyzed the current conditions of the west of Shandong Province and tried to find the generation mechanisms of current non-balanced economic development of Shandong Province. And then approaches to regional development were put forward according to the theory of regional development pattern as a whole.     

Quantitative Appraisement on Ecological Carrying Capacity in Coastal Rapid Developing Region of Hainan Province

Abstract

The ecological carrying capacity, an important indicator to evaluate the sustainable development of the ecosystem, means the potential ability of the natural ecosystem to carry socioeconomic development while the ecosystem is healthy. It is limited by the carrying capacity of natural resources and environment and the elasticity of the ecosystem. It will be greatly significant to study the ecological carrying capacity of Hainan Province, the first ecological province admitted by the State Environmental Protection Administration in China. Not only is the natural ecosystem reflected, but also the effects of human activities are emphasized by integrating the ecosystem health analysis into the ecological carrying capacity research. The research results, using the Factor Analysis tools of software SPSS, indicate that the ecological carrying capacity of Hainan Province fluctuated obviously from 1996 to 2005. The level of the ecological carrying capacity of Hainan Province was relatively high in 1996, and reached into trough from 1997 to 1999. It has steadily ascended to be above the middle level since the 21st century. The results also show that policy factors, especially the implementation of the ‘Ecological Province’ strategy, were important driving forces to influence the ecological carrying capacity. With the population rapidly increasing, the land and water resources per capita have decreased quickly. The amount of the ecological carrying capacity was promoted remarkably by socioeconomic development especially economic growth and technology applications. All of these will provide useful suggestions to establish and enact regional development policies, especially for protecting and reconstructing the ecology and environment of Hainan Province.     

空间视角下湖北省环境绩效评估及影响因素分析

以湖北省为例，基于压力-状态-响应（PSR）模型构建环境绩效评估指标体系，运用空间自相关和标准差椭圆对湖北省各地区绩效指数空间特征及影响因素进行探讨，结果显示：湖北省各地区环境绩效指数（EPI）均高于60，但普遍处于中等水平，良好及优秀所占比例低.EPI较高的地区主要位于湖北省西部和中部，压力和状态指数从西至东递减，响应指数则呈现东部高于西部高于中部的态势.状态指标绩效指数在空间上显著正相关，即环境质量状况较好（或较差）的地区在空间上集聚.EPI及二级指标绩效指数均以西北-东南为布局方向，且EPI椭圆重心较于基准重心偏向于西南方向.各地区环境指数除受到资源禀赋的影响外，还与城镇化率和人口密度显著相关.     

江西灾害性强雷电天气的雷达回波特征

使用常规地面报表A0资料、多普勒天气雷达资料,以及雷电数据和卫星云图等资料,进行了雷电和雷暴日的分布特征统计分析,重点对灾害性强雷电天气的雷达回波特征进行个例分析,以了解雷电和雷暴天气的活动规律和强雷电的雷达回波特征,提高预警预报的能力.结果表明:(1)雷电和雷暴天气具有明显的季节变化与日变化特征,每年2-5月集中在8-20时,6-9月集中在11-20时;(2)强雷电天气在雷达回波上表现为南北走向的回波带结构,当回波强度≥50dBZ、回波出现不断合并现象、强回波水平尺度较大、具有"指状"或"弓状"回波结构,以及出现陡直"零值线"和VIL超过50 kg/m2时,最易发生强雷电天气;(3)有时局部强单体凭着自身的发展,当强度≥50dBZ和VIL超过50 kg/m2时,也有可能出现局地强雷电天气.
