河北省张宣葡萄产区土壤地球化学特征

[目的]为科学合理规划特色农产品种植区,因地制宜地扩大张宣葡萄种植规模。[方法]文章通过对张宣葡萄产区开展1:5万农业生态地质现状调查,利用土壤地球化学测试数据,与河北省平原区背景值、张家口盆地背景值进行对比分析,归纳总结研究区土壤地球化学特征;并依据土地质量和土壤环境质量相关规范,对张宣葡萄产地进行系统地土壤肥力和土壤环境质量评价。[结果]葡萄种植区土壤中铜、锶、二氧化硅、氧化钾含量较高,尤以铜最为显著,含量均值是张家口盆地背景值的2倍,是河北省平原区背景值的1. 94倍;铬、镍、铁、锰、氮、有机碳、硒、镁含量相对较少,均低于张家口盆地背景值和河北省平原区背景值。整体而言,土壤综合肥力相对缺乏,主要表现为氮、磷缺乏;土壤环境综合质量较为清洁,无Ⅲ类区,全部重金属元素均未超风险管制值,99. 26%的面积低于全部重金属元素风险筛选值,表现为4个样点铜含量和1个样点镉含量高于风险筛选值,分别位于宣化区和涿鹿县境内。[结论]应通过增施化学肥料提高土壤中氮、磷含量,注意防治保护性杀菌剂的使用带来的铜局部累积现象。

Stakeholder perceptions and governance challenges in urban protected area management: The case of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area,Philippines

The conservation and management of protected areas in urban settings has become increasingly challenging with dynamics over land use change in adjacent urban areas being highly relevant to, but at times conflicting with, the protected area. This study seeks to better understand the implications of land use change processes to urban protected area management through the case study of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) in Metro Manila, Philippines. Factors and processes influencing land use change and protected area management and the impact of stakeholders’ perceptions on protected area were analyzed. The urban protected area in itself has limited influence on its surrounding urban areas, as land use change in these areas is shaped more by social, economic and policy/institutional factors occurring within the context of urban-regional development. The study also found that land use conflict is evident in an urban protected area due to the competing ecosystem services derived by various stakeholders. This discord is deepened by the lack of coordination between land use planning and protected area management. Integrating protected area management with land use planning through legally binding instruments, specific timeframes and clear internal procedures can help resolve land use conflict for an urban protected area at the strategic or policy level.

Ecotourism as a conservation tool and its adoption by private protected areas in Brazil

Ecotourism in private reserves combines the establishment of protected areas with an incentive mechanism to conserve biodiversity. Brazil's private reserve system is well-established but little is known about its links to tourism. This study puts the global private protected area into context and quantifies the extent to which ecotourism has been adopted as a sustainable land-use practice on private reserves in Brazil. Our findings demonstrate that small reserves do contribute to conservation and are used for ecotourism. The belief that large reserves are necessary for ecotourism and conservation is challenged. Only 4% (n = 45) of the 1182 reserves are engaged in ecotourism, mainly those within the Atlantic Forest biome and these are generally small in size (<50 ha). Reserves provide modest to basic accommodation as well as education and economic opportunities that include adjacent communities. Hiking and bird watching are the most popular activities but many reserves are threatened by poaching and invasive species. The low adoption of ecotourism appears due to a combination of factors, including lack of landowner interest, constraints imposed by regulations, logistics and anthropogenic threats. Nonetheless, there is potential to expand ecotourism within private reserves as 143 further private reserves are located near those already engaged in ecotourism.     

城市功能拓展区域文化产业园发展路径研究

城市功能拓展区既缺少核心区集聚的文化资源优势,又缺少郊区低廉的发展成本优势,但在着力发展文化创意产业的过程中,却可以通过整合文化产业园区资源,形成独特的发展优势.本文运用商业生态学理论,分析城市功能拓展区内文化产业园区发展的“三元”联动主体,构建园区资源整合的双重主体理论,并提出文化产业园区确定主导产业并吸引核心企业以“聚核”、拓展纵向产业链和横向服务链以“聚链”、打造公共平台并进行功能体系建设以“聚网”的“三聚”持续发展路径.

现代林业运营绩效评估研究——以新疆为例

论述新疆现代林业运营现状,建立现代林业运营绩效评估体系,应用ANP方法确定评估指标的局部优势度与全局优势度,构建现代林业运营绩效评估模型,科学测度2005~2014年新疆现代林业运营绩效,结果表明:新疆现代林业运营整体绩效呈现上升趋势,但整体水平薄弱;新疆干旱区营林生产、林产加工绩效弱化且波动显著,林业生态与服务、林业发展贡献绩效持续优化;森林病虫害防治低下、林业生态建设用水投入量减少、家具制造业优势不足、传统林业产业项目路径锁定等是制约新疆现代林业运营绩效的关键因素。为切实提升新疆现代林业运营绩效,提出建立森林病虫害生态防治机制、确保林业用水安全、提升家具等木材精深加工产业的技术增值能力、加快推进林产加工业结构调整、持续挖掘林业旅游与特色林果业的发展潜能等建议。     

亚太区域贸易协定的经济增长效应*——基于RTAs数量与质量的对比研究

21世纪以来，亚太地区区域贸易协定（RTA）签署的数量激增，学术界理论与现实出现悖论，引发学者思考各国热衷于建立RTAs背后的原因并探索新的研究方法。本文首次从RTAs数量和质量的影响效应哪个更为重要的视角，将发达国家和发展中国家进行对比分析，深入探究发达国家在新时期推进新一代贸易协定规则的原因。通过比对RTA协议的每一条条款，测算出涉及传统WTO+和新一代WTO-X领域的条款覆盖率和法定承诺率指标来衡量RTA的质量，实证分析得出，签署高质量的区域贸易协定能更有效地推动亚太地区的经济增长和人民福利水平的提高，该影响效应在发达国家中更为明显，而发展中国家受限于执行能力在新一代规则下签订RTA对经济增长的作用不显著。
