湖北省旅游经济空间差异研究

以湖北省17个市为研究的区域单元,以2002～2006年各市的旅游外汇收入、国内旅游收入为基础数据,分析了省内旅游经济存在的空间差异。结果表明湖北省外汇旅游经济差异和国内旅游经济的绝对差异和相对差异都在扩大。研究阐述了影响这种差异的因素,并提出了缩小差距的对策。     

旅游干扰对喀纳斯景区草地植物多样性的影响

研究喀纳斯景区旅游干扰下草甸草地群落的植物多样性,利用主要物种重要值、α多样性、功能群重要值和β多样性比较分析不同干扰后群落植物多样性及结构功能的变化。结果表明:随着干扰强度的增加,群落物种组成从以不耐旅游干扰的物种为主逐渐发展到以耐旅游干扰的物种为主,群落的重要值有向少数物种集中的趋势;Patrick丰富度指数和Shannon-Wiener指数均随着干扰强度的增加而呈下降趋势,均匀度指数则在中度干扰下最大,生态优势度的变化与α多样性的变化存在一定的负关联;功能群丰富度在中度干扰下最高;中度-重度干扰阶段群落间的物种替代速率最快。喀纳斯景区草甸草地群落稳定与群落自身的物种多样性、功能群功能特性及结构特点密切相关。     

林兆璋“旅游设计组”时期园林建筑创作观解析

“旅游设计组”是指以莫伯治、佘俊南两位院士为首，活跃在20世纪六七十年代岭南地区的城建设计团体，该设计组的建筑师在岭南地区留下了诸多以简洁园林提升建筑空间品质的经典作品。建筑师林兆璋（1938—2022）是该组的重要成员之一，以林兆璋在“设计组”时期（1964—1982）主要参与创作的园林建筑空间为对象，从技术观、时代观、艺术观3个层面解析其创作观念，研究拓展了岭南当代风景园林史视野，有助于建筑师、风景园林师了解那个关键转折期的设计思潮。     

樱桃番茄NFT栽培技术

NFT栽培是一种能够解决植物连作障碍、减轻农药使用，同时具有干净、观赏性强等特性的水培技术。樱桃番茄富含VC、营养价值高，成串坐果，作为水果食用，将樱桃番茄应用NFT技术进行栽培较传统叶菜水培更具观赏性，且可用于家庭园艺和采摘园区，对生态农业和观光农业具有示范作用。     

Land use choices in a changing world

The primary factors which are likely to mould future non-urban land use patterns in Australia are identified. Over the past three decades the rate of increase in land productivity in Australia has been higher than for any other OECD country. Land degradation does not appear to have seriously threatened agricultural output over the last 45 years. However, there is cause for concern that land degradation, attributable to past activities, may only now be exerting a significant impact on productivity in some regions. Many of the services provided by natural resources have been underpriced; consequently, there has been a bias in agricultural research towards technologies that enhance on-site productivity, but which impose excessive external social costs. Underpricing of native trees from state-owned and managed forests appears to have caused excessive exploitation of these forests and lowered the establishment of softwood and hardwood plantations. Many important land use and land cover issues remain unresolved in Australia's rangelands, including questions relating to the optimum grazing pressures, the role of fires in the suppression of unpalatable shrubs and appropriate management strategies for controlling numbers of large kangaroos and rabbits and protecting the natural habitat of threatened species of native animals. The riparian zone, which acts as a crucial buffer between rivers and their catchments, has been one of the most neglected environments in Australia, possibly because river banks, floodplains and wetlands do not fit neatly into the category of land or water. It is widely accepted that the aboriginal peoples must be involved in seeking to achieve the sustainable use of our natural resources. How to achieve the appropriate participation and involvement of aboriginal peoples is a problem that is yet to be fully resolved. In many respects, renewable natural resource systems in Australia are unique. Knowledge creation and application will be a most important resource for the future management of our agricultural forestry and natural resource systems. The solutions to many of the major renewable resource problems do not depend on technology alone. Institutional changes and incentive structures are required that recognize and take account of the pervasive and complex interrelationships between human reactions and responses in their production and consumption activities and the environment.
