Despite continuous investment and various efforts to control pollution, urban water environments are worsening in large parts of the developing world. In order to reveal potential constraints and limitations of current practices of urban water management and to stimulate proactive intervention, we conducted a material flow analysis of the urban water system in Kunming City. The results demonstr...

In the process of urbanization, maintaining ecosystem health in ecologically fragile regions is an inevitable requirement for sustainable development future, but ecological status varies greatly at different spatial scales. Determining appropriate scale assessment basis and premise management environmental protection policy making. Taking Dianchi Lake basin as research area, based on vigor-orga...

Peat soil is widely distributed in the Dianchi Lake area of Yunnan, and effect cement deep-mixing method on peat foundation mainly affected by humic acid (HA). In this paper, a composite curing agent formed adding different proportions ultra-fine (UFC) to ordinary Portland (OPC) used cure HA-containing cohesive soil. Mercury intrusion porosimetry (MIP), scanning electron microscopy (SEM), X-ray...

Algal blooms frequently occur in numerous lakes China, risking human health and the environment. In contrast, aquatic vegetation contributes to water purification. Due similar spectral characteristics shared by algal vegetation, both are hardly distinguishable remote sensing imaging, especially turbid bodies. To address this challenge, study constructed a method effectively extract from bodies ...

磷的外源输入与底泥源汇变化是湖泊富营养化形成的重要原因,解析磷出入湖关键过程及其平衡变化对湖泊环境治理具有重要意义。本研究针对滇池外海出入湖磷通量变化问题,融合水文水质观测数据和HBV水文模型模拟数据,使用LOADEST负荷统计模型解析了2001-2018年滇池外海入湖河流、大气沉降和出湖河流的磷通量变化特征,评估了湖体总磷的源汇效应及其影响因素。结果表明:①2001-2018年滇池外海入湖磷通量年际间波动范围大,在118~700 t/a之间,多年平均入湖磷通量为280.61 t/a,其中河流平均输入251.97 t/a,大气沉降平均输入28.64 t/a,在研究的气象水文因子中,入湖磷通量主要影响因素是入湖流量和调水量,其次是降水;②滇池外海年均出湖总磷通量42.25 t/a,在8~84 t/a 之间波动,出湖通量变化主要受入湖流量与调水量的影响,其次是气温;③在年和月的时间尺度上...
