Ecological risk assessment is a key measure of ecological environment management. Assessing the ecological risk at regional scale has practical significance in strengthening ecosystem...
To identify the inhalable particle matter (IPM) sources and to estimate the variability in their contributions to inhalable particle concentrations across the Beijing city, the spatial distribution of PM0.3, PM1.0 and PM3.0 concentration are simulated by monitoring data obtained from 93 air sampling stations in Beijing urban city and Kriging techniques. Inhalable particles in this study had aerodynamic...
The purpose of this paper is to develop a framework of ecological vulnerability assessment, and to assess the ecological vulnerability by this framework in the middle and lower reaches of the Hanjiang River Basin. Based on the theory of cause - and - consequence, we proposed an indicator system of ecological vulnerability assessment at basin scale. Twelve indicators are selected to constitute the...
