Research on the spatiotemporal evolution and trade-offs of ecosystem services (ESs) is important for optimizing ecological security barrier system promoting coordinated socio-economic development. Natural factors, e.g., climate change, human unreasonable land use, have impacted damaged structure function, leading to challenges with ES spatial identification priority protected areas. Here, characteristics five ESs (water yield, nitrogen export, soil retention, carbon storage, habitat quality)...
In order to understand the community characteristics of macroinvertebrates in Qingyijiang River, a survey was conducted September 2020 and July 2021. this paper, change water quality analyzed by using environment comprehensive index, niche further substitution method based on occurrence frequency species, simulated null distribution breadth Mantel test. The results are revealed as follows: (1) There were significant changes number between 2021, but no composition (percentage taxa); (2)...
Abstract Rapid urbanization has brought numerous aquatic problems to plain river network regions. We selected three categories (five indicators) of characteristics describe the physical systems, including quantitative, structural, and complex characteristics. Using grid method hierarchical clustering analysis (HCA), spatiotemporal change pattern one Yangtze River Delta was addressed from 1960s 2014 based on topographic maps. The results showed that density ( D R ), water surface ratio W P...
River islands are sandbars formed by scouring and silting. Their evolution is affected several factors, among which runoff sediment discharge. The spatial-temporal of seven river in the Nanjing Section Yangtze China was examined using TM (Thematic Mapper) ETM (Enhanced Thematic Mapper)+ images from 1985 to 2015 at five year intervals. following approaches were applied this study: threshold value method, binarization model, image registration, cropping, convolution cluster analysis. Annual...
As one of the most developed regions in China, plain East China is undergoing gradually increased flooding under obvious urbanization process. This paper mainly analyses trend water level time series region during past decades, and assesses temporal spatial variation indicators hydrological alteration. The results show that there a increasing level. Bigger slope higher significant can be observed monthly minimum than maximum level, peri-urban urban areas. Meanwhile, it mean both regions,...
Using analytic hierarchy process and entropy method to determine the weight of index, fuzzy comprehensive evaluation model risk assessment was constructed in this paper.Flood index rating area along Yangtze River Anhui province were drawn by using GIS spatial analysis technology.From disaster causing factors, inducing environment bearing body, average maximum 3 day rainfall, rainstorm number, vegetation coverage, river network density, standard deviation elevation, population proportion...
Abstract The diversity of functional traits macroinvertebrates in freshwater ecosystems is one the current research hotspots field biodiversity. Understanding trait composition and their factors can make study watershed beta river ecological security patterns more effective. Based on two surveys conducted September 2020 July 2021 Qingyijiang (QYJ) River, longest tributary south bank lower Yangtze River China, we explored compositions relationships between water environment using indices,...
Rivers and streams are recognized as potential greenhouse gas (GHGs: CO2, CH4, N2O) sources, contributing to global warming. However, GHG emissions from rivers have received insufficient attention compared other ecosystems (forests, grasslands, wetlands, etc.). In this study, dissolved concentrations were measured in the Qingyijiang River, longest tributary lower reaches of Yangtze during two campaigns September 2020 April 2021. Our results showed that River was oversaturated with GHGs. The...
The Little Ice Age (LIA) during the Ming and Qing dynasties was most abnormal climate event in China for nearly 2,000 years. During this period, relatively cold various natural disasters frequently took place. By locating compiling related historical documents, we aimed to quantitatively systematically analyze spatial–temporal variations ancient Huizhou region (hereinafter referred as or Huizhou) (1368–1911; all dates are AD, unless otherwise mentioned). results show that (1) flood drought...
