Urbanization intensity (UI) affects habitat quality (HQ) by changing land patterns, nutrient conditions, management, etc. Therefore, there is a need for studies on the relationship between UI and HQ quantification of separate urbanization impacts HQ. In this study, direct indirect were analyzed Yangtze River Delta Urban Agglomeration (YRDUA) from 1995 to 2010. The results indicated that regional was nonlinear negative, with inflection points where reached 20% 80%. Furthermore, depending...
Water provision service is crucial for human society to survive and develop. It essential evaluate the importance of sub-watersheds, based on their different capacities provide water resources manage an entire watershed. Previous studies have assessed sub-watershed by analyzing its supply and/or demand service. However, few considered influence spatial flow. In this study, we proposed assessment framework that combined supply, demand, flow The Qiantang River Basin in China was selected as...
Biodiversity maintenance is a crucial ecosystem service. Due to time limits and data availability, assessing biodiversity using indicators or models has become hot topic in recent decades. However, whether some proposed can explain well at the local scale still unclear. This study attempted test habitat quality index (HQI) as measured integrated valuation of services trade-offs (InVEST) model could variations bird diversity New Jiangwan Town, rapidly urbanized region Shanghai, China. The...
The Z-scan technique has been successfully used to determine the magnitudes and signs of fifth-order optical nonlinearity induced by two-photon absorption. Here, it was investigate saturable-absorption (SA) a charge-transfer salt (TBA)2Ni(dmit)2 (TBA = tetra-n-butylammonium, dmit 2-thioxo-1,3-dithiole-4,5-dithiolate) with 1064 nm pulses. Under excitation these pulses, titled molecule exhibits typical SA effect at relatively low levels intensity, while showing strong excited-state absorption...
Antibiotics in water have attracted increasing attention due to their potential threat aquatic ecosystems and public health. Most previous studies focused on heavily polluted environments, while ignoring urbanized rivers with high population density. Taking Suzhou Creek Shanghai as an example, this study attempted explore the antibiotic pollution characteristics of typical rivers. Further, it screened out priority antibiotics so provide reference for regular monitoring urban surface study’s...
The optical nonlinearity of (TBA)2Ni(dmit)2 (TBA = tert-n-butanyl-amonimium, dmit 1,3-dithiol-2-thione-4,5-dithiolate) at high incident irradiance was investigated using Z-scan technique with 1064 nm picosecond laser pulses. This molecule shows a strong absorption band ranging from 900 to 1600 nm. Under excitation by 1064nm pulses, this exhibits typical saturable-absorption (SA) due transition, and negative third-order contribution nonlinear refraction (NLR). result indicates that it...
In this paper, combining refractive and diffractive effects, a new kind of infrared lenses with wavelength 10.6 mu m was designed produced for CO2 laser material processing. This refractive-diffractive lens (RDL) converts beam into the rectangular shape light intensity distribution in concave at x-direction. A method which employs input aperture division geometrical transformation technique obtaining better initial phase iteration is presented. The experimental results show that desired...
