Improving Operational Planning and Management of National Parks in Turkey: A Case Study

The purpose this study was to improve operational planning and management of national parks in Turkey to balance conservation use and sustainable management. Souksu National Park (SNP) was chosen as the study area. The data were obtained from interviews of 182 visitor groups (in total, 819 people) and analyzed using correlation, factor, discriminant, and regression analyses. It was found that the most important factors affecting operational planning and management of SNP are (1) travel cost, (2) visitor welfare level, (3) intensity of use, (4) size of visitor group, (5) type of recreational demand. The main source of visitors to SNP is from a zone within a 0–90-km radius. This region comprised 53.85% of total visitors to the park. The capital of Turkey (Ankara) is the most important source of visitors from within this zone. The optimum activity mix in SNP is also determined. Picnicking, viewing the scenery, and nature walks or trekking comprised the main uses of the park. It is anticipated that these findings will help to improve operational planning and sustainable management of the national park and the environment.

长江口中华鲟保护区及临近水域大型底栖动物研究

根据2004年5月、8月、11月和2005年2月(Ⅰ年度)及2005年8月、11月和2006年2月、5月(Ⅱ年度)共2个水文年对T长江口中华鲟保护区水域(30°15′～31°45′N、121°30′～122°15′E)15个取样站8个航次的采泥样品和阿氏网样品,对底内动物和底上动物的种类组成、生物量、栖息密度、重要种的优势度、群落多样性和结构及时间空间动态变化进行分析.结果表明,底内动物共出现15种,种类组成贫乏,优势种变化明显,底内动物生物量和栖息密度平均值分别为1.44 g/m2和11.33个/m2,生物量和栖息密度总体呈现下降趋势,物种多样性指数低并有下降趋势,群落结构极不稳定;底上动物底栖动物59种,组成有明显季节和年度变化,底内动物生物量和栖息密度平均值分别为15.58 ×10-2g/m2和6.81×10-2个/m2;底上动物生物量和栖息密度略呈现下降趋势,优势种的种类及优势度年际有较大变化,种类数和生物量北支高于南支.底内动物2个年度生物量平均值季节变化为夏季＞春季＞秋季＞冬季,底上动物2个年度生物量平均值季节变化为春季＞冬季＞秋季＞夏季,底内动物与底上动物的季节变化具有一定的不平衡性.     

平衡——生态健康之刁——平衡与生态健康之关系

“平衡”是世间万物之本,而生态健康却与自然、社会、政治以及人体平衡等有着千丝万缕的联系。随着人类社会经济的不断发展和人们生活水平的不断提高,生态健康已成为现代化生活的一个重要标志,它直接关系到人们的健康生活。本文提出了“平衡”是生态健康之本,从一个新颖的视角一“平衡”,简明地论述了平衡在人类的生存发展过程中的重要性,以及它与生态健康之间的密切关系。文章中阐述的观点值得思考,对如何理解和审视“生态健康”有着重要的启示作用。     

Carbon footprint of food - approaches from national input-output statistics and a LCA of a food portion

The aim of the study, on which this paper is based, was to provide guidance to consumers to make environmentally responsible choices in their food consumption, to assist food supply chain stakeholders to identify the key areas for environmental improvements, and to provide policy makers with a tool for monitoring the potential impacts on climate change resulting from developments within the food sector. At the macro level, the EIO-LCA model was developed specifically for the Finnish food chain; at the micro level, LCAs were performed on 30 lunch portions. The contribution of the Finnish food chain to climate change was 14%, which comprised 40% CO₂ emissions, 25% CH₄ emissions, and 34% N₂O emissions. The share of impacts from domestic agricultural processes was the highest, at 69%. The impact of a single lunch portion ranged between 0.65 and 3.80 kg of equivalent CO₂. According to the EIO-LCA model, the average impact was 7.7 kg CO₂ eq/person daily. The consumer phase accounted for between 8 and 47% of the climate change impacts for homemade portions. In ready-to-eat portions industry and retail phases were emphasized, representing 25-38% of climate change impacts. We present an approach to steer the Finnish food sector onto an environmentally sustainable path; practical tools for consumers and farmers will especially need to be developed further.     

GKS在国家水质管理信息系统中的应用

图形核心系统是开发图形应用软件的一组核心功能描述,它独立于设备和各种高级语言,自８０年代中期被ＩＳＯ正式批准为第一个计算机图形学国际标准以来,世界上各大计算机厂商纷纷推出ＧＫＳ不同级别的实现版本,广大用户也不断将自己的图形应用开发平台转向ＧＫＳ。本研究结合国家水质管理信息系统的需求,以ＧＫＳ为起点,完成了ＮＷＱＭＩＳ图形管理系统的设计与实施,有效地支持了其应用功能的实现。     

国家科技发展规划与中国的资源科学

国家先后编制了七次科技发展规划,资源科学研究也从最初的自然资源综合考察发展成了一门综合性交叉学科。其中以《1956-1967年科学技术发展远景规划》和《1978-1985年全国科学技术发展规划纲要》,对资源科学的形成与发展影响最大。前者推动了中国自然资源综合考察事业的形成与发展,后者促进了中国资源科学考察事业的发展与壮大,进而推动了资源科学的形成与发展。全文在回顾与展望国家科技发展规划与中国资源科学发展的基础上,提出了新世纪初期国家中长期科学技术发展规划有关资源科学发展的3条建议。
