中国农业生态补偿法律制度建设研究

2014年通过的《环境保护法》第31条规定:国家建立、健全生态保护补偿制度.紧随其后,2014年5月苏州市人大常委会正式批准了《苏州市生态补偿条例》,彰显了国家和地方政府对于生态补偿这一法律制度的重视.农业生态补偿作为生态补偿的一个具体分支,法律制度的建设,将对当前中国日趋严重的农业面源污染问题,提供一个现实的解决路径.文中找出农业生态补偿法律制度存在的问题,并提出具体的建设意见,为中国农业生态补偿法律制度的建设提供理论上的支撑.     

Case Study Comparing Multiple Irrigated Land Datasets in Arizona and Colorado,USA

While there are currently a number of irrigated land datasets available for the western United States (U.S.), there is uncertainty regarding in how they relate to each other. To help understand the characteristics of available irrigated datasets, we compared (1) the Cropland Data Layer (CDL), (2) Moderate Resolution Imaging Spectroradiometer Irrigated Agriculture Dataset (IAD), (3) Digitized Irrigated Land (DIL), and (4) Consumptive Use for Irrigation (CUI) data in Arizona and Colorado, U.S. These datasets were derived from multiple sources at various spatial resolutions and temporal scales. We found spatial and temporal trends among all of them. The datasets showed decreases in irrigated land area in Arizona during the 2000–2010 time period. The change ranges and ratios were similar in all Arizona datasets. Irrigated land in Colorado decreased in DIL and CUI but increased in IAD and CDL. The agreement within the same type of dataset during different time periods was from 60% to 80% (R² from 0.35 to 0.72) in Arizona and from 50% to 80% (R² from 0.23 to 0.68) in Colorado. DIL had the highest agreement (80%) in both states. The agreement among different datasets acquired at approximately the same time frame ranged from 51% to 63% (R² from 0.14 to 0.31) in Arizona and from 47% to 69% (R² from 0.32 to 0.40) in Colorado. The results from this study support a greater understanding of the multiresolution and multitemporal nature of these datasets for various applications.

海峡两岸自然保护区比较研究

８０ 年代以来,海峡两岸在自然保护区建设方面都取得了较大成绩,但双方交流甚少,缺乏相互了解。本文重点对海峡两岸的自然保护区建设现状以及管理体制、分类系统、管理状况等进行了比较分析,并就如何进一步加强相互交流和促进中国自然保护区事业的发展提出相应的对策建议。     

Animal agency in wildlife conservation and management

Wildlife conservation and management (WCM) practices have been historically drawn from a wide variety of academic fields, yet practitioners have been slow to engage with emerging conversations about animals as complex beings, whose individuality and sociality influence their relationships with humans. We propose an explicit acknowledgement of wild, nonhuman animals as active participants in WCM. We examined 190 studies of WCM interventions and outcomes to highlight 3 common assumptions that underpin many present approaches to WCM: animal behaviors are rigid and homogeneous; wildlife exhibit idealized wild behavior and prefer pristine habitats; and human–wildlife relationships are of marginal or secondary importance relative to nonhuman interactions. We found that these management interventions insufficiently considered animal learning, decision-making, individuality, sociality, and relationships with humans and led to unanticipated detrimental outcomes. To address these shortcomings, we synthesized theoretical advances in animal behavioral sciences, animal geographies, and animal legal theory that may help conservation professionals reconceptualize animals and their relationships with humans. Based on advances in these fields, we constructed the concept of animal agency, which we define as the ability of animals to actively influence conservation and management outcomes through their adaptive, context-specific, and complex behaviors that are predicated on their sentience, individuality, lived experiences, cognition, sociality, and cultures in ways that shape and reshape shared human–wildlife cultures, spaces, and histories. Conservation practices, such as compassionate conservation, convivial conservation, and ecological justice, incorporate facets of animal agency. Animal agency can be incorporated in conservation problem-solving by assessing the ways in which agency contributes to species’ survival and by encouraging more adaptive and collaborative decision-making among human and nonhuman stakeholders.     

防洪工程信赖对公众洪灾风险认知的影响——以开封沿黄地区与岳阳洞庭湖区为例

防洪工程作为人类抵御洪灾的首选手段,为人们提供了保障,但人们对其风险认知还存在一定的偏差。本文从公众层面入手,在我国历史上洪灾最严重的两大流域—长江流域和黄河流域,分别选取岳阳沿洞庭湖区和开封沿黄河地区为研究区,调查公众对当地防洪工程的信赖状况和水灾风险认知情况,回收有效样本831份。据此分析影响防洪工程信赖的因素和工程信赖对公众风险认知的影响。研究发现,公众对防洪工程的信赖度较高,区域趋同性明显;公众对工程信赖的程度,因居住地与风险源的距离、性别、年龄和家庭劳动力结构的不同而存在差异;同时,对防洪工程的过于信赖,会降低公众对洪灾的恐惧心理和警惕性,并使得公众产生消极和积极并存的应对灾害的行为倾向。洪灾多发地区应建立大型洪灾、巨灾的风险防范和洪水保险机制,完善我国的再保险制度;政府在高风险区的分区域管理过程中,应以大局为重;构建"文化自觉"的科学防灾文化观,正确引导公众认识到工程措施能力的限度,扭转在工程信赖基础上的风险认知偏差。     

我国区域道路交通安全形势对比与影响因素分析

根据2007年的政府统计数据,将全国划分为4个社会经济发展区域,并对比各区域道路交通的发展状况与安全形势,然后运用SPSS统计软件分析道路交通安全评价参数与社会经济发展水平之间的相关性。发现社会经济发展梯次靠前的区域,其道路交通与安全状况也相对较好;GDP、人口、机动车保有量、机动车驾驶证普及率、道路条件和交通运输规模等因素分别对交通事故的死亡人数、万车死亡率、亿元GDP死亡率和百公里道路死亡率等指标具有显著影响。针对各区域的道路交通安全现状,必须进一步加快交通基础与安全设施建设,建立和完善交通事故紧急救援体系,加强交通安全宣传、教育、管理以及区域间的交流与合作。     

美、英、澳职业安全健康业绩指标及对我国借鉴的研究

基于我国安全生产统计及业绩指标体系发展现状,研究美国、英国及澳大利亚的职业安全健康统计指标体系,为我国完善职业安全健康体系提供借鉴。研究得出,美、英、澳3国的职业伤亡统计以工作单位为统计范围,国家统计部门定期汇总、公布因工作原因造成的死亡、伤害或职业病数据。统计指标使用死亡人数、可记录伤害人次数、损失工作日数及相应的比率等。认为我国应明确职业安全健康统计范围、统计边界、统计对象,以利于准确评估安全生产业绩;建立可记录伤害和损失工作日天数统计标准,改革安全生产统计指标,以满足行业通用、国际对比。     

交通运输企业交通事故法律适用问题探讨

交通运输企业的交通运输事故法律适用问题引起了社会广泛争议。如不明确这个问题,对于执法主体、执法权限就不能明确,既会产生安全管理的盲区,有时候也会损害企业的相关权益。文章对《中华人民共和国安全生产法》适用范围条款进行了分析解读,阐明道路交通运输企业的交通运输安全问题既适用《安全生产法》,也适用《道路交通安全法》,二法之间不会有交叉,更不会产生冲突;同时也对道路交通事故的属性进行了分析,并探讨了交通运输企业交通事故的法律适用问题。
