“…Urban lakes play a pivotal role in reclaimed water resource utilization and the development of urban environments [ 1 ]. In the past few decades, an increasing number of man-made urban lakes used for recreation have been built around city parks in order to increase the quality of the living environment for citizens [ 2 , 3 ]. Recently, urbanization has been improved due to the rapid industrialization in developing countries [ 4 ].…”

Urban lakes play a vital role in the sustainable development of urbanized areas. In this freshwater ecosystem, massive microbial communities can drive the recycling of nutrients and regulate the water quality. However, water bacterial and fungal communities in the urban lakes are not well understood. In the present work, scanning electron microscopy (SEM) was combined with community level physiological profiles (CLPPs) and Illumina Miseq sequence techniques to determine the diversity and composition of the water bacterial and fungal community in three urban lakes, namely Xingqing lake (LX), Geming lake (LG) and Lianhu lake (LL), located in Xi’an City (Shaanxi Province, China). The results showed that these three lakes were eutrophic water bodies. The highest total nitrogen (TN) was observed in LL, with a value of 12.1 mg/L, which is 2 times higher than that of LG. The permanganate index (CODMn) concentrations were 21.6 mg/L, 35.4 mg/L and 28.8 mg/L in LG, LL and LX, respectively (p < 0.01). Based on the CLPPs test, the results demonstrated that water bacterial communities in the LL and LX urban lakes had higher carbon source utilization ability. A total of 62,742 and 55,346 high quality reads were grouped into 894 and 305 operational taxonomic units (OTUs) for bacterial and fungal communities, respectively. Water bacterial and fungal community was distributed across 14 and 6 phyla. The most common phyla were Proteobacteriaand Cyanobacteria. Cryptomycota was particularly dominant in LL, while Chytridiomycota and Entomophthormycota were the most abundant fungal phyla, accounting for 95% of the population in the LL and 56% in the LG. Heat map and redundancy analysis (RDA) highlighted the dramatic differences of water bacterial communities among three urban lakes. Meanwhile, the profiles of fungal communities were significantly correlated with the water quality parameters (e.g., CODMn and total nitrogen, TN). Several microbes (Legionella sp. and Streptococcus sp.) related to human diseases, such as infectious diseases, were also found. The results from this study provides useful information related to the water quality and microbial community compositions harbored in the aquatic ecosystems of urban lakes.

“…Therefore, the western countries led by the United States have put forward various rain flood management concepts or practices. The original purpose of the best management measures for rain and flood is to control non-point source pollution through engineering or non-engineering measures (Zhang J et al 2017) [8]. In the course of subsequent development, these measures have been extended from the initial simple engineering or non-engineering measures into systematic measures to complete the systematic control of urban runoff and pollution (Jiang Y et al 2017) [9].…”

The construction of sponge city has become an important way to coordinate the balance between human development and natural ecological environment. Therefore, the research on the coupling planning of the coastal sponge city in the framework of Pressure-State-Impact-Respond (PSIR) was put forward. On the basis of detailed analysis of the characteristics of sponge city and PSIR framework, a whole set of coastal sponge city matrix coupled planning index system was put forward. With the information technology used as the main technical means to monitor, the researchers analyze and evaluate the system. Finally, the system was illustrated and analyzed with Xiamen city, Fujian province as an example.

“…Researchers have different focuses on zoning functional areas of sponge city [56,57], but they did not consider the issue from the perspective of the integrity of the urban ecosystem. The sponge city is a strategy for integrated urban water management to construct benign interactions between the social-economic system and the urban water cycle [58].…”

Waterlogging is becoming a severe and universal phenomenon in China, so the construction of sponge cities is proposed to address urban water problems abiding by the overall principles of ecological priority and low-impact development. The ecological security pattern (ESP) is an effective way to balance rapid urbanization and ecological protection. Taking Zhengzhou as an example, this study, performed a geographic information system (GIS) modeling, which constructed a targeted ESP for the construction of a sponge city based on comprehensive analysis of multi-factor water ecological sensitivity. Compared to previous studies of ESP, some improvements were made in the identification method of ecological sources, corridors, and nodes. By analyzing the ESP, the study divided the whole city into different construction zone. Through different protection and planning strategies for these areas, the integration and connectivity of the ecological sources can be improved, and thus, urban ecological security can be improved. The ESP for sponge city is a relatively more systematic and scientific way to guide the construction of a sponge city, and can be used for reference to other cities in the process of sponge city construction.
