Lake Xingyun is a hypertrophic shallow lake on the Yunnan Plateau of China. Its water quality (WQ) has degraded severely during past three decades with catchment development. To better understand external nutrient loading impacts WQ, we measured concentrations in main tributaries January 2010–April 2018 and modelled monthly volume all for same period. The results show annual inputs total nitrogen (TN) had higher variability than phosphorus (TP). multi-year average load was 183.8 t/year TN...
湖泊水体表层温度是气候和环境变化的重要指示因子,遥感技术是水体表层温度监测的重要手段。温度反演算法在不同湖库水体的适用性各异,针对清洁型深水湖库的水体表层温度反演算法适用性仍有待进一步研究。本研究以千岛湖为研究区,利用Landsat 8卫星数据,对比了基于辐射传输方程的算法(RTE)、单窗算法(MWA)、普适性单通道算法(GSCA)、实用单通道算法(PSCA)、劈窗算法(SWA_D和SWA_G)和Landsat 8 Collection 2 Level-2(C2L2)温度产品的精度,探究了各算法中相关参数的适用性和敏感性,刻画了千岛湖2013-2021年水体表层温度时空分布特征。研究结果表明:(1)针对Landsat 8数据的第10和11波段,千岛湖最适宜的水体比辐射率分别为0.9926和0.9877;(2)整体上,劈窗算法的精度优于单通道算法,Landsat温度产品的估算精度适中。其中,劈窗算法SWA_G精度最优,平均相对误差(MAPE)为7.61%,均方根误差(RMSE)为2.0...
Data support for wetland protection function evaluation can be provided by quantitatively analyzing the ability of regulating regional climate ecosystem. In this study, cold-humid effect Baiyangdian was analyzed comparing meteorological conditions and its surrounding areas. Meanwhile, regulatory functions processes magnitudes temperature relative humidity from August to October 2008 were evaluated. The results show that daily mean temperatures in lower than areas, differences mainly occurred...
Based on the one-year hourly water temperature profiles and associated environmental drivers during past eight years in Shahe Reservoir, Jiangsu Province, China from 2009 to 2016, factors underlying seasonal variation of thermal stratification quality response were investigated. It was shown that a typical subtropical one-cycle mixing model, lasting May September. The appeared disappeared when surface 21 ℃ late spring 19 middle autumn. difference between at epilimnion hypolimnion increased...
<p>A main cause of water eutrophication in lakes or reservoirs are nutrient enrichment, which variations can be influenced by climatic changes and anthropogenic activities. It was reported that rainfall may lead to a short-term increase nutrients threaten the quality reservoirs. Daily meteorological data collected over last few years Lake Qiandaohu basin highlight an frequency extreme events. The relationships between (nitrogen phosphorus) concentrations lake external loading...
The MO properties of Co/Pt multilayers (MLs) depend fundamentally on the periodic structure multilayers. In this paper, influences Co layer thickness, atom proportion and Pt, sputtering temperature are studied. results prove that strongly thickness Pt. When t<SUB>Co</SUB> < 0.4 nm, t<SUB>CO</SUB>/t<SUB>Pt</SUB> equals 1/2, have better comprehensive properties; when substrate is raised up to a proper degree, crystallinity improved obtained, which finally improves We also studied factors...
