基于学科基本要素分析的流域生态学学科评价

Disciplinary assessment of watershed ecology outlined by essential ingredients of discipline

在20世纪中后期,中国逐渐开始关注流域层面生态环境问题,提出流域生态学,那是一个时代的机遇。而在21世纪的今天,中国生态环境问题已呈现出越来越强的流域性特征,发展流域生态学,则是一个时代的任务。流域生态学被作为一门学科提出来,截至目前近20年,发展不尽人意。本文从学科承认、学科评判标准的视角分析讨论流域生态学的学科发展现状。分析结果显示,学科身份对于流域生态学的发展具有重要价值;流域生态学目前依然处于一个初创阶段,学科的内在建制和外在建制都未形成。

In the mid and end of the 20 th century,when China began to pay attention to the ecological and environmental problems at a watershed level,it was a call of the times to propose watershed ecology. Today,in the 21 st century,China's ecological and environmental problems manifest increasingly typically watershed-wide features,and it is the most urgent task to develop watershed ecology.watershed ecology as a new discipline had been proposed for nearly 20 years,but still developed poorly. Against the value of disciplinary recognition and the essential ingredients of discipline,we analyzed the status of watershed ecology. The results showed that:(1) disciplinary recognition was important for the development of watershed ecology.(2)watershed ecology was still in a start-up phase of a discipline,neither inside institution nor outside institution.
