生态空间·人本生活———华南师范大学校园环境景观的初步评价

从生态学的角度,人本思想为理念,从空间和形态上,通过建筑、水体、植被、道路和景观小品等方面,对华南师范大学校园环境景观进行了初步的评价.探索如何营造一个人文环境和自然环境和谐共存、整体完善的高校校园生态环境系统.     

源于盲分离思想的线性变形图象校正

本文从盲分离思想入手，利用反馈式社会经网络，根据Ｈｅｂｂｉａｎ学习算法，对二维线性变形二值图象的校正问题提出了一个新的解决方法，并对分离状态的稳定性进行了讨论，最后给计算机的模拟结果。     

晚唐五代江浙隐逸文学生态研究

晚唐五代江浙隐逸文学的复盛,与中原文化第二次向南推移的历史背景密切相关。杨吴、南唐及吴越政权的偏安与稳定,为地域性文学生态的改善提供了历史契机;九华山、西山、庐山、奉化、永嘉等地,相继成为隐逸作家聚集交流的胜地。由道士、僧侣及出世文人共同组成的创作群体,借助隐逸文学表达了独特的生活境遇和价值理想,同时呈现出一种乱世特有的静谧与安闲。不过,其作品时常体现出偏狭和无奈的情态。     

Study on the Technology of Restoration and Giving a New Lease of Life to the Alpine Grassland Vegetation in the Construction of the Qinghai-Tibet Railway

This article gives a summary and analasis to experimental study on the restoration and giving a new lease of life to the alpine grassland vegetation along the Qinghai-Tibet Railway. Through on-the-spot investigation and vegetaion storation experimental study to the constructive fetching soil ground in Tuotuo River experiment section in the construction of the Qinghai-Tibet Railway, the result shows ： after the activities of the construction, soil conditions on the fetching soil ground have changed a lot, the soil quality has obviously degraded. In order to do well the vegetaton storation and reconstruction in the process of the construction of the Qinghai-Tibet Railway, the backfilling of the surface soil should really be done well. According to the result of on -the-spot experiment, the Elymus dahuricus Turcz and Poa annua Linn are all more suitable to the fetching soil environment on the alpine grassland, the plant can normally grow in the growing season. The timing selection of the vegetation should fully use feature of both rain and heat in the same season, thus can improve the percentage of success.     

基于生态学理论的工业生态系统比较研究

本文从工业系统的生态性入手,与传统的生物生态系统做以比较分析。以物质循环和能量流动为重点,主要从相似性、相异性两个个方面比较分析了工业生态体系。对生态工业园建设及循环经济的开展有一定的参考价值和指导意义。     

河流生态修复浅议

河流与人类社会发展息息相关,具有重要的社会意义.在人类社会的发展过程中,自然河流逐渐渠道化、非连续化,城市河流更是开发过度、污染严重.近年来,河流的生态问题受到广泛关注,人们开始重新认识和利用河流,提出了河流牛态修复的理念.本文对河流生态修复的理念进行了阐述.提出了河流生态修复的原则,之后从生态护岸、水质改善、生态景观建设3方面对现行的河流生态修复技术进行了说明.     

矮岩羊种群的生态学资料

利用路线调查方法分别于1998年7-8月和2000年7-8月对巴塘县的矮岩羊（Pseudois schaeferi）种群进行了初步研究，结果显示，从20世纪50年代以来，矮岩羊的种群数量下降很快，目前主要栖息在巴塘县的竹笆笼到苏阿龙一带河谷及支流两侧陡峭的、难以攀越的悬崖绝壁上的岩壁草丛环境中，面积大约200km^2的范围内，数量大约在141只左右，活动群体的大小为2-10只，种群平均密度为0.705只/km^2，矮岩羊生性胆小，易受惊吓，休息时喜欢用前脚刨地，约占休息时间的1/3。森林面积的锐减，人为猎杀，过渡放牧是影响矮岩羊种群数量和生存环境的主要原因。     

Nurse plant theory and its application in ecological restoration in lower subtropics of China

urse plants are those that facilitate the growth and development of other plant species (target species) beneath their canopy because they offer benign microhabitats that are more favorable for seed germination and/or seedling recruitment than their surrounding environment. Nurse plants have been mainly used to restore vegetation in arid and sub-arid zones in recent years. Based on summarizing the definition of nurse plant and target plant, we review the nursing effect mechanisms, ecological factors that influence nursing effect, relationships between nurse plant and ecological restoration. This review also brings forward possible pairs of nurse and target species at lower subtropical areas. Furthermore, we provide the potential tendency in nurse plant research and application.     

生态全息论初探

用全息科学及系统全息的思维方法,探讨了生态系统中生物与环境统一体内生态差异性的同一性及其本质——生态全息性,阐述了生态全息理论,生态全息论认为,全息现象在生态系统中普遍存在,生态圈是一个最大的全息生态系统,各子系统在一定程度上都是它的缩影。文中还论述了生态全息律、生态重演律等。生态全息论的提出对于确立新的生态整体观,建立新的生态工程,研究生态系统的发展和进化,对于预测、控制等都具有重要的理论价值和实践意义。
