【摘要】 花岗岩侵蚀山地生态重建及其生态环境效应 人类对环境的压力,导致生态环境的恶化。对生态的恢复与重建随着人们环境意识的提高而日益受到政府、社会和科技工作者的重视。本文对亚热带分布广泛的花岗岩侵蚀山地的生态重建问题以及重建后所产生的生态环境效应展开研究,目的是为了寻求合适的生态重建途径。生态恢复与重建是一个理论性与实践性都很强的工作,惟有二者紧密结合,方能有效。研究工作正是以此为立足点,以大量的第一手的监测资料、调查资料、具体的实践资料为基础,进行分析和理论上的提高。研究所取得的主要结论包括:(1)系统分析和总结了花岗岩生态系统的特征,及其退化的特征和过程,指出花岗岩生态系统存在若干退化过程阶段,不同的阶段应采用不同的重建方法;(2)生态重建途径的选择要因地制宜,因经济和社会的发展而变化;(3)应用“3S”技术,可把景观生态学的理论与生态重建活动进行有机的结合。(4)进行各种恢复与重建措施后的土壤、植物群落、小气候等生态环境的研究,认为生态恢复与重建后的生态环境效应是评价生态系统服务功能及重建效果的基础。更多还原

【Abstract】 Pressure from human being on the environment has led to the deterioration of eco-environment. Nowadays, having recognized the importance of environment, the whole society, especially scientific and technological circles, is paying more and more attention to the problem of restoration and rehabilitation of the ecological environment. This paper is on the study of rehabilitation of eroded granite mountainous regions that are widely spread across subtopics and the ecological and environmental effects after the rehabilitation. The purpose of this study is to seed for suitable ways for rehabilitation. The author believes that the restoration and rehabilitation of ecology must be combined together, and it is a job strongly associated with both theory and practice. On account of this, the study, which is based on a great amount of data of monitoring, investigation and practice, analyzed the data and draw the conclusions as follow:1) By analyzing the features and process of the formation and degeneration of granite ecosystem, the author points out that there are various degeneration phrases, and in different phrases, there should be different methods of rehabilitation.2) The methods of rehabilitation of ecosystem should be taken in the light of local conditions and they should be varied according to the development of local economy and society.3) The application of "3S" will result in the integration of theory of landscape ecology and practice of ecological rehabilitation.4) Having studied the ecosystem such as soil, phytocoensis and microclimate after restoration and rehabilitation, the author believes that theeffectiveness of ecological environment after the restoration and rehabilitation is the criteria of evaluating the serving function of ecosystem and the effects of rehabilitation.更多还原
