| 2 | Spatio-temporal Changes in Water Conservation Ecosystem Service During 1990–2019 in the Tumen River Basin, Northeast China显示文摘The water conservation(WC) function of ecosystems is related to regional ecological security and the sustainable development of water resources, and the assessment of WC and its influencing factors is crucial for ecological and water resource management.The Tumen River Basin(TRB) is located in the core of the Northeast Asian ecological network and has been experiencing severe ecological crises and water shortages in recent years due to climate change and human activities. However, these crises have not been fully revealed to the extent that corresponding scientific measures are lacking. This study analyzed the spatial and temporal evolution characteristics and drivers of WC in the TRB from 1990 to 2019 based on the water yield module of the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST) model. The results showed that: 1) under the combined effect of nature and socioeconomics, the WC depth of the TRB has slowly increased at a rate of 0.11 mm/yr in the past 30 years, with an average WC depth of 36.14 mm. 2) The main driving factor of the spatial variation in WC is precipitation, there is a significant interaction between precipitation and velocity, the interaction between each factor is higher than the contribution of a single factor, and the interactions between factors all have nonlinear enhancement and two-factor enhancement. 3) Among the seven counties and municipalities in the study area, the southern part of Helong City and the southeastern part of Longjing City are extremely important areas for WC(> 75 mm), and they should be regarded as regional water resources and ecological priority protection areas. It is foreseen that under extreme climate conditions in the future, the WC of the watershed is under great potential threat, and protection measures such as afforestation and forestation should begin immediately. Furthermore, the great interannual fluctuations in WC depth may place more stringent requirements on the choice of time scales in the ecosystem service assessment process. | ZHANG Peng LIU Xiaoping ZHU Weihong LI Chunjing JIN Ri YAN Hengqi GU Chengyang WANG Jingzhi | 2023 | Chinese Geographical Science2023，33，1： | 0 |
| 3 | Self-Assembly of Crystalline Vesicles from Nonplanarπ-Conjugated Nanocycles显示文摘There is a great demand for self-assembled carbon nanomaterials because of their importance in optoelectronics,biomaterials,and so forth.Herein,we report a novel type of self-assembled,nanoscale,crystalline vesicle from nonplanarπ-conjugated nanocycles.We designed four different structural[8]cycloparaphenylenes([8]CPPs)molecules and demonstrated that these nonplanarπ-conjugated CPP nanocycles could self-assemble into multilamellar,crystalline vesicles in tetrahydrofuran(THF)/H2O mixed solvent. | Huang Tang Zhewei Gu Chengyang Qiao Zhibo Li Wei Wu Xiqun Jiang | 2021 | CCS Chemistry2021，3，7： | 0 |
