| 摘要: |
| 为回应对《洞庭湖地质环境系统分析》系列研究成果提出的质疑,在理论分析、宏观时空分析以及大量举证的基础上,论证了构造沉降对近代洞庭湖演变起着主导作用。作者利用地形图比对求算的洞庭湖堤围区视构造沉降速率,不仅与重复水准测量成果一致,还得到有关中国大陆第四纪以来构造活动加剧的研究成果的定性支持。作者在研究中应用的“假设-演绎法”是一种富有创造性的科学方法。因此,《洞庭湖地质环境系统分析》的基本结论是成立的。 |

| Abstract: |
| This paper is a reply to the queries about research results of “Dongting Lake geology environmental system analysis”. Based on theoretical and macroscopic analysis, together with a series of reliable evidence, tectonic subsidence plays a leading role in modern Dongting Lake evolution. The apparent tectonic subsidence rate in the embanked area of Dongting Lake calculated by authors has been supported both by leveling data and tensification of tectonic movement in continental China since the Quaternary Period. The hypothesis-deductive method applied by the authors is a kind of creative scientific research tool. The basic conclusions of “Dongting Lake geology environmental system analysis” are reliable. |
