Ecosystem service spatial transfer is considered a feature that can deliver ecosystem services at distance to meet the demands in areas with uneven distribution of natural and social economic development. The ES intensity were simulated by using modified breaking point model Central Plains urban agglomeration (CPUA) cities Luoyang, Zhengzhou, Shangqiu, Huaibei stretching across. It shown there ...

Catch Per Unit Area (CPUA) estimation and distribution pattern of pharaoh cuttlefish from North Coast Gulf Oman

We report on results of a trawl survey to assess the abundance of Batoid fish resources in the Oman Sea. The catch per unit area CPUA as the main index was estimated. The objectives of this study were to determine the catch composition and distribution pattern of Batoid fishes in the study area and in different depth strata of the Oman Sea.A total of 82stations were randomly selected 2012. The ...

Groundwater function zoning is an important means to ensure that groundwater plays its various functions, which can provide a scientific basis for the protection and development of resources. Water resources are scarce in Central Plains Urban Agglomeration (CPUA), so it great significance evaluate vulnerability zone this area. In study, resource supply (RSF), eco-environment (EEF), geo-environm...

This paper explores the relationship between high-speed rail (HSR) and industrial agglomeration within urban agglomerations. The selects data of Beijing–Tianjin–Hebei Urban Agglomeration (BJHUA) Central Plains (CPUA) from 2002 to 2016 as research object. time-varying difference-in-difference (TVDID) model is innovatively applied analyze impact HSR on secondary tertiary industries in agglomerati...
