黑河生态水量调度项目实施后,尾闾湖水面恢复并扩大,绿洲得到灌溉,气象灾害减少,土壤水分条件改善,生产力增加。随着河道通水天数的增加,地下水系统得到补充,地下水位持续下降的趋势得到初步遏制,并逐渐回升,2006年地下水位达到或接近1995年以来的历史最高值。绿洲面积增大的同时,局部地区林草覆盖度逐年提高。56.51%的受调查者对生态水量调度项目有基本认知,他们相信退化环境,像沙尘暴、森林退化和生物多
Urbanization has both direct and indirect impacts on land use change, and analyzing spatio-temporal characteristics of land use change is essential for understanding these impacts. By comparing Landsa
In post-reform China, local governments, instead of the central state, have become major promoters of urbanization. Differing from the existing literature based on Western theories, this article argue
Employing decoupling index and industrial structure characteristic bias index methods, this study analyzed the spatial-temporal characteristics of industrial structure transformations and their result
Land use structure optimization(LUSO) is an important issue for land use planning. In order for land use planning to have reasonable flexibility, uncertain optimization should be applied for LUSO. In
The aquatic ecosystem maybe significantly affected by polycyclic aromatic hydrocarbons(PAHs) released from fresh water sediments. In order to protect biodiversity, the spatial distribution and sources
The Chinese National Antarctic Research Expedition(CHINARE) was established and first reached the Antarctic in 1984. Up until 2017, China has undertaken 33 cruises to Antarctica, and seven cruises to
The Arctic is one of the most sensitive regions that respond through feedback to global climate changes. Climatic, hydrological and ecological changes in the Arctic are clear evidence of global warmin
To improve our understanding and ability to predict biological responses to global climate change, it is important to be able to distinguish the influences of natural forcing from anthropogenic impact
China launched its Arctic research program and organized the first Chinese National Arctic Research Expedition(CHINARE-Arctic) in 1999. By 2016, six further expeditions had been conducted using the R/
