龙感湖演变驱动力分析及生态保护策略

为了解龙感湖演变的主要驱动力和作用机制,对龙感湖地区的气候、地质等自然因素和和人类活动等进行分析.研究结果表明:龙感湖浅水型、草型湖泊的特征在其演变过程中始终发挥着作用;在千年尺度上,气候因素在龙感湖演变中起主导作用;800a左右人类活动的加强,尤其是近100a来龙感湖区域经济社会的发展,人类活动成为控制龙感湖演变的主导因素.围湖造田和水利工程的建设是人类对龙感湖产生影响的主要方式,在此基础上,提出了龙感湖的保护对策.

Evolution Driving Force Analysis and Ecological Protection Strategies for Longganhu Lake

In order to know the main driving force and acting mechanism of evolution about Longganhu lake,the environmental factors(climate,geology) and human activities were analyzed.The results showed that the characters of grass-type and shallow lake played important roles all the way,and the major factor was climate at the millennial scale.With the strengthening of human impacts around 800 years,especially with the development of economy and society in the recent 100 years,human activities became the dominant factor in Longganhu Lake evolution.The main ways that human affected the process of Longganhu Lake were building dikes from lakes and the levee constructions.Based on all of these,the protective countermeasures were further proposed in the paper.
