关君蔚先生水土保持科学思想回顾

A review on Professor GUAN Junwei's scientific ideologies in soil and water conservation

关君蔚先生生前带领团队创办了我国第一个水土保持专业,成为全国水土保持教育、科学研究、水土保持管理与实践人才的摇篮,培养和造就出的大批水土保持专业科学技术人才。关先生在长期的防护林研究与建设实践中,对于山区、丘陵区、黄土高原区、干旱风沙区等不同区域的防护林林种组成及其配置、结构及其功能等方面提出了独到的见解,提出"立地条件"和"适地适树"的原理,奠定了我国防护林体系建设的理论基础,开创了一条适合我国国情的防护林体系建设的道路。他一生还系统地研究了泥石流发生与运动规律,并建立了泥石流预测预报方法。关先生将大系统控制论与可持续发展理论应用与水土保持与荒漠化防治,提出了生态控制系统工程的理论,从东方思维的视角,分析生态系统演化、功能、效应和人类的适应,对人与自然关系及其有机协调的论述,为我国水土保持与荒漠化防治事业提出了新的理论与方法。

[Background]This review is for the tribute to Professor GUAN Junwei at his 100th anniversary birthday.[Methods]We are Professor GUAN爷s students,have learnt his knowledge system,and understand Mr.GUAN爷s academic achievements,thus we are trying to review them here.[Results]The discipline of water and soil conservation in China was firstly established by Professor GUAN Junwei and his team,which has been a cradle for education,science and research,management and practice of water and soil conservation,bringing up a majority of excellent and talents in water and soil conservation field.In the long-term research and construction practice of protection forest,Professor GUAN proposed original theories and unique understandings on the composition of protection forest species and its configuration,structure and function in different areas such as mountainous area,hilly area,the Loess Plateau area,arid and sandy area,etc.He presented principles of“site conditions and“matching species with the site,laid the theoretical foundation for the construction of protection forest system in China,and carved out a road which suits the construction of protection forest system under our national circumstances.Throughout all his life,he also studied the occurrence and movement of debris flow,and systematically established prediction methods of debris as well.Professor GUAN applied large system control and sustainable development theories into soil and water conservation and desertification evolution,function,effect and human adaptation from the perspective of oriental thinking.He discussed the relationship between man and nature and their organic coordination,and offered new theories and methods for the practice of soil and water conservation and desertification control of our country.Professor GUAN's contribution to the science of soil and water conservation in China has won the recognition of the academic field and he was selected as an academician of the Chinese Academy of Engineering in 1995.[Conclusions]We understand his strict academic philosophy and noble style as a teacher while reviewing his academic ideologies,from which we in the field of soil and water conservation benefit.We will work as Professor GUAN did and take challenges in the deterioration of global environment and ecological construction during drastic development of economy in China.
