| 中文摘要:中国大陆水圈是地球水圈的重要组成部分。青藏高原的阶段性急剧隆起和全新世以来的持续上升，控制着中国大陆水圈的自然演化方向和速率。中国大陆水圈演化在研究地球陆地水圈方面有其特殊意义。近几十年来，随着国民经济建设的发展及人类工程技术活动的加强，导致地表河流流量及入海水量减少、地下水位大面积下降和地面沉降、地表水和地下水水质恶化、海水入侵地下水含水层等等，这些都积极地改变着中国大陆水圈的自然状态，从而影响人类的生存环境。因此，开展中国大陆水圈演化研究──中国大陆水圈量与质的演化过程、中国大陆水圈与其它圈层间的相互作用、人类社会经济活动对中国大陆水圈演化影响与反馈、水环境演化趋势及资源环境效应预测等，不仅是我国地球科学与国际研究接轨的需要，也是保护人类生存环境最基本的重大课题。 |

| Abstract:The China continental hydrosphere is an important component part of global hydrosphere. Therapid uplift by stage and continuous uprising of Qinghai-Tibet plateau since the Holocene epoch domi-nates the natural evolution direction and evolution speed of China continental hydrosphere,which is ofparticular significance in studying global continental hydrosphere. In the past a few decades,the rapid development of the national economy construction and the in-crease of mankind’s enginerring activities gave rise to the decrease of flowrate of surface rivers andwater quartity into the sea,decline of groundwater level in large area as well as land subsidence,dete-rioration of both surface water and groundwater and sea water intrusion into groundwater aquifers.Allof these have drastically changed the natural state of China continental hydrosphere,thus affecting themankind’s living environment.Therefore,to make the study on the evolution of China continentalhydrosphere,covering the subjects such as the quartity and quality evolution process of China conti-nental hydrosphere,the interaction between the China continental hydrosphere with other spheres,in-fluence and feedback of mankind’s social and economic activities on China continental hydrosphereevolution,water environmental evolution tendency and prediction of resouce environment effect arenot only the need of conbining geoscience study in China with that of the world,but also the most fun-damental task to protect mankind’s living environment. |
