风景林景观抗旱植物选择与造景

我国是世界上缺水最严重的干旱区之一，因而研究抗旱植物在风景林遣景中的应用，在水资源问题日益突出的今天就具有特别重要的意义。过去的风号林景观规划存在重视景观效果而忽视抗旱植物对其少以利用的现象。文章拟在综合抗旱兼观赏性良好的植物种类中挑选出不同的搭配组合予以应用到风景林遣景中去，并对这些抗旱植物种类进行分类，对它们的生长习性和园林应用进行介绍，使之符合风景林景观抗旱植物的选择与造景的规划设计理念，进而指导实践工作。     

临床专升本学生与临床本科学生心理卫生对照研究

目的了解临床专升本与普通本科学生心理健康状况差异。方法采用心理卫生自评量表(SCL—90),对82名专升本同学和85名临床本科学生进行调查。结果临床专升本学生SCL—9强迫、人际关系、抑郁、敌对、偏执、精神病性、阳性项目数高于全国常模,差异有统计学意义。(t值为3.76,2.24,3.36,3.11,2.51,6,12.95,P<0.001)。普通本科学生强迫、精神病性方面高于全国常模,差异有统计学意义。(t值分别为1.5,3.39,P<0.01)。专升本学生的人际关系敏感、抑郁、敌对因子分与本科五年制学生相比较有显著性差异(P<0.05)。专升本心理问题发生率为57.4%,普通本科学生心理问题发生率为27.1%。结论临床专升本学生与临床本科学生相比较有较明显的心理问题,应进行重视及进行相应的干预。

Managing field margins for biodiversity and carbon sequestration: a Great Britain case study

Abstract. Field margins are a valuable resource in the farmed landscape, providing numerous environmental benefits. We present a preliminary analysis of the carbon mitigation potential of different field margin management options for Great Britain, calculated using data from long-term experiments and literature estimates. The carbon sequestration potential of the individual options investigated here varies from 0.1 to 2.4% of 1990 UK CO₂-C emissions, or 0.7–20% of the Quantified Emission Limitation Reduction Commitment (QELRC). The scenarios investigated covered three possible margin widths and options for the management of margins at each width (viz. grass strips, hedgerows and tree strips). Scenarios involving margin widths of 2, 6 or 20 m would require approximately 2.3, 6.7 or 21.3% of the total arable area of Great Britain, respectively. Scenarios including tree strips offered the greatest potential for carbon sequestration, since large amounts would be accumulated in above-ground biomass in addition to that in soil. We also accounted for the possible impacts of changed land management on trace gas fluxes, which indicated that any scenario involving a change from arable to grass strip, hedgerow or tree strip would significantly reduce N₂O emissions, and thus further increase carbon mitigation potential. There would also be considerable potential for including the scenarios investigated here with other strategies for the alternative management of UK arable land to identify optimal combinations. We assumed that it would take 50–100 years for soil carbon to reach a new equilibrium following a land use change. More detailed analyses need to be conducted to include environmental benefits, socioeconomic factors and the full system carbon balance.     

目录直读图片管理系统的设计及实现

目录直读图片管理系统是一个新型的图片管理系统.许多非计算机专业的电脑爱好者在使用以往的图片管理软件时,大多都只能进行自己能力范围内的修改,在数据库的使用上则出现了不少问题.目录直读图片管理系统的最大特点就是只有一个单文件,没有数据库,这样就巧妙的解决了非计算机专业电脑爱好者所头疼的问题.本文着重阐述了目录直读图片管理系统中,图片管理的实现策略、关键技术、实现方案等.

Management challenges of small-scale fishing communities in a protected reef system of Veracruz, Gulf of Mexico

Abstract  Socioeconomic characterisation of fishing activities in the Veracruz Reef System National Park was used to develop a management system which balances the community's livelihood, and the conservation needs of the protected area. A survey was applied to four sectors of the fishing community: the fishers, fishers' wives, retailers and local population. The survey determined their perceptions about: (1) fishing as a lifestyle; (2) economic alternatives; (3) perspectives about the future; (4) environment; and (5) knowledge of the National Park as a protected area. Fishers devoted an average of 27 years fishing, investing an average of 12 h per day giving a regular income of 15–20 US$. Most interviewed (60%) were full-time fishers, with fishing the only family income source. Fishers are predominately educated to primary school level (64%).The main problem faced by fishers and the communities were economic opportunities but 89% believed that mariculture could be an alternative income source. There was strong ecological awareness, with 75% aware of the decline in fisheries resource and 62% knowing about the role of protected areas. There was divided opinion about future perspectives. Inefficient organisation and communication between authorities and fishers were identified as obstacles to co-management. Discussion on alternative incomes and a proposal involve fishers in co-management initiatives are presented.
