Some lakes in China have undergone serious eutrophication, with cyanobacterial blooms occurring frequently. Dynamic monitoring of is important. At present, the traditional lake-survey-based bloom spatiotemporally limited and requires considerable human material resources. Although satellite remote sensing can rapidly monitor large-scale blooms, clouds other factors often mean that effective ima...

The construction of ecological security patterns is an effective means to improve environment quality, protect regional biodiversity, and alleviate the landscape fragmentation caused by urbanization in plateau lake cities. Taking Dianchi Lake area as example, we used morphological spatial pattern analysis method (MSPA) minimum cumulative resistance model (MCR) construct a comprehensive surface,...

大泊口位于滇池草海南部,水域面积0.52 km2,平均水深约2 m,作为滇池草海重富营养化水域生态修复示范区,大泊口分别于2015和2019年开展了两期生态修复工程,经过近年来的系统治理,大泊口水生态治理效果初步显现。为分析探究成功修复湖区水质改善、生态系统企稳向好的原因,本研究选择2015年2月-2021年12月共7年的连续监测数据,根据工程开展情况以及水生态状况将大泊口水域划分为4个部分(A1~A4水域),首先分析4个区域内主要的水质指标(悬浮物(SS)、化学需氧量(CODCr)、总磷(TP)、总氮(TN)和叶绿素a(Chl.a))的变化趋势和相关性,其次探究不同类型生态工程的修复效果,最后与草海和外海水域进行对比,分析大泊口的治理效果。结果表明,治理后大泊口A1~A4水域的CODCr、TP和Chl.a稳定下降,C...

As different algae growths responding to a set of nutrients can occur under conditions, the nutrient load management based on relationship between chlorophyll (Chla) and total phosphorus (TP) alone may not always effective for lake bloom control. It is clear whether lagged response reduced related utilization efficiency (UEAP), how UEAP could climate water quality factors. Here we analyzed over...

Land use change is widely regarded as a key factor altering the structure and function of ecosystems. Urbanization particular driver influence in land expanding globally, especially developing countries like China. The InVEST model was employed this study to comprehensively assess temporal-spatial impacts urban changes (ULUC) on ecosystem services (ESs) clarify tradeoffs between urbanization pr...

The water quality of a basin is pronouncedly affected by the surrounding types land use. Analyzing impact LULC and landscape patterns on critical for identifying potential drivers. To further study how LUCC affects in typical plateau lake basin, this investigated impacts land-use Dianchi Lake Basin Southwest China. We analyzed changes pattern calculated CWQI (Canadian Water Quality Index) value...

Efficient, comprehensive, continuous, and accurate monitoring of organic pollution in lakes can provide a reliable basis for water quality assessment prevention This paper takes Dianchi Lake as the research object, aiming at four important indexes permanganate index (COD), dissolved oxygen (DO), hydrogen ion (pH), ammonia nitrogen (NH3-N); based on correlation analysis Landsat 8 data measured d...

Periphytic algae is frequently utilized as a health indicator for ecosystems. Many research studies have been conducted in China on the periphytic community, but none has compared community structure at inflow rivers among different lakes Yangtze river basin. The were investigated 94 sites of Dianchi Lake, Danjiangkou Reservoir, Dongtinghu Poyanghu Chaohu and Taihu Lake. Based microscopic resea...
