On June 22 - 27, Atal Bihari Vajpayee, India' s Prime Minister, paid a fruitful visit to China. The Prime Ministers of the two sides signed a programmatic document for the development of relations 'Declaration on Principles for Relations and Comprehensive Cooperation between the People's Republic of China and Republic of India.' ① They also concluded nine related agreements. The events showed that Sino - Indian relations have entered a new phase of development. The two governments should continue to make every effort to elevate the good - neighborly and friendly relations of mutual benefit and cooperation to a new level, thus laying a more solid foundation for a long - term development of ties between China and India.

The Aral Sea Basin in Central Asia is an important geographical environment unit in the center of Eurasia.It is of great significance to the ecological protection and sustainable development of Central Asia to carry out dynamic monitoring and effective evaluation of the eco-environmental quality of the Aral Sea Basin.In this study,the arid remote sensing ecological index(ARSEI)for large-scale arid areas was developed,which coupled the information of the greenness index,the salinity index,the humidity index,the heat index,and the land degradation index of arid areas.The ARSEI was used to monitor and evaluate the eco-environmental quality of the Aral Sea Basin from 2000 to 2019.The results show that the greenness index,the humidity index and the land degradation index had a positive impact on the quality of the ecological environment in the Aral Sea Basin,while the salinity index and the heat index exerted a negative impact on the quality of the ecological environment.The eco-environmental quality of the Aral Sea Basin demonstrated a trend of initial improvement,followed by deterioration,and finally further improvement.The spatial variation of these changes was significant.From 2000 to 2019,grassland and wasteland(saline alkali land and sandy land)in the central and western parts of the basin had the worst ecological environment quality.The areas with poor ecological environment quality are mainly distributed in rivers,wetlands,and cultivated land around lakes.During the period from 2000 to 2019,except for the surrounding areas of the Aral Sea,the ecological environment quality in other areas of the Aral Sea Basin has been improved in general.The correlation coefficients between the change in the eco-environmental quality and the heat index and between the change in the eco-environmental quality and the humidity index were–0.593 and 0.524,respectively.Climate conditions and human activities have led to different combinations of heat and humidity changes in the eco-environmental quality of the Aral Sea Basin.However

为探究博落回(macleaya cordata)在不同施氮梯度下各生育期生物量及总生物量分配的动态变化规律,设置5个施氮水平:CK(0 kg·hm^(−2))、N_(1)(75 kg·hm^(−2))、N_(2)(150 kg·hm^(−2))、N_(3)(225 kg·hm^(−2))、N_(4)(300 kg·hm^(−2)),从2020年起开展为期两年的连续施氮试验,揭示博落回在贫瘠土壤中的生长适应特征。结果表明:1)N_(3)、N_(4)各时期博落回的冠生物量、根系生物量和总生物量均显著高于CK、N_(1)和N_(2)(P<0.05)。2)博落回的根冠比在不同年份有差异,第1年所有处理的根冠比在6月最低,分别为0.04、0.12、0.09、0.15和0.16,第2年在8月最低,分别为0.20、0.18、0.08、0.06和0.10;2021年6月和8月,CK的根冠比都高于其他处理。3)2020年10月N_(3)的茎叶比显著高于其他处理(P<0.05),其他处理的茎叶比各月份间差异不大;2021年各处理间茎叶比随恢复时间逐渐增加,在11月达到最大,分别为2.82、1.19、1.23、1.89和2.05。综上所述,建议对煤矿复垦区博落回施加225~300 kg·hm^(−2)的氮,以此来促进博落回在贫瘠土壤中的快速定植,本研究可以为缺氮土壤中博落回的生长适应性研究提供理论依据。

The Sichuan-Tibet Railway,mainly located in the southeastern Qinghai-Tibet Plateau,is affected by summertime extreme precipitation(SEP).Using daily rain-gauge observations and ERA5 reanalysis data for the summers of 1979-2020,the spatiotemporal distribution characteristics of SEP in the key region of the Sichuan-Tibet Railway(28°-33°N,90°-105°E,hereafter KR)are revealed,and the mechanism for SEP amount(SEPA)variation in the KR is investigated.The results show that SEPA in the KR contributes nearly 30%to the total summer precipitation.Regional differences are evident in SEP,justifying thresholds higher in the plateau-dominated central-western KR(CWKR)and lower in the basindominated eastern KR(EKR).In addition,SEP in the CWKR is less intense but more frequent than SEP in the EKR.During 1979-2020,the SEPA in the KR increased slightly while the SEPA in the CWKR increased significantly and peaked in the last decade.When anticyclonic circulation(AC)anomalies dominate the 500 hPa pattern over the Bay of Bengal and Mongolia,the southerly flow and cyclonic shear over the southeastern plateau will be strengthened,favoring more SEPA in the CWKR.When an AC anomaly dominates the 500 hPa pattern over the Bohai Sea,the low-level easterly wind over the basin will be strengthened,favoring more SEPA in the EKR.The strengthening of the ascent,water vapor convergence,and convective instability is conducive to more SEPA in the KR.Our results deepen the understanding of the characteristics and the physical mechanisms responsible for extreme precipitation in the KR.

Changes in the weather will cause variations in the hydrological system.Arid areas,with fragile hydrological systems,are very sensitive to changes in the weather,so the coupling analysis of short-term weather and runoff in arid areas is of great significance.The Daihai Lake is a closed inland lake in an arid area of China.In this paper,Weather Research and Forecasting model mode-Hydrological module(WRF-HYDRO)is used to simulate the coupling of weather and hydrology in the Daihai Lake Basin.Regional optimization of WRF-HYDRO is carried out to determine the optimal parameters.The optimal WRF-HYDRO model is applied to couple the short-term weather and runoff in the Daihai Lake Basin to reproduce several rainstorm and flood events.It is found that runoff infiltration parameter(REFKDT)in WRF-HYDRO is the parameter that has the most severe effect on runoff in the Daihai Lake Basin.WRF-HYDRO can capture the rainstorm moment of the rainstorm events in the Daihai Lake Basin,especially the first rainstorm moment,and its simulation accuracy is good.WRF-HYDRO has a strong ability to capture flood peak,but there is a discrepancy between WRF-HYDRO flood peak and Soil Conservation Service Curve Number(SCS-CN)calculation result at the flood peak moment.The northern part of Zuoyun County should guard against the occurrence of flood disaster in wet season.The coupling of weatherand hydrology can not only make up for the lack of runoff data in arid basins,but also provide a basis for water resources management and disaster prevention and mitigation in the basins.

In recent years, both China and India have paid great attention to the energy security issue. As they are both big energy consumers and importers, launching energy cooperation between China and India is mutually beneficial. Cooperation between the two countries should stick to the following principles: strengthening communication; avoid unnecessary conflict; advancing technical exchange and jointly promoting the stability of the world energy market.
