Parameters of vegetation spatial structure have important effect on the carbon cycle and biodiversity of the ecosystems. How to estimate above-ground biomass is still a problem need to be worked out. In this paper we tried to use UAVSAR datasets to discuss the relation between backscattering coefficient and local incidence angle in different forest types. By the relation, a method based on scattering...
Wetland is a significant component of the land ecosystems to discover the characteristics and ecological laws. Presently, a common method to estimate a regional wetland biomass is normally based on optical remote sensing images. The estimation of wetland biomass by Synthesize Aperture Radar (SAR) is a novel subject. As a new type sensor, SAR has advantages for wetland applications, therefore, it can...
The management of recreational fishing is a controversial subject in most jurisdictions. On the one hand, recreational fishing provides substantial economic benefits. Fishing activities, on the other hand, can threaten valuable fish stocks and cause damage to marine environments. However, most management strategies undertaken so far tend to be ad hoc and not supported by proper modeling. To address...
An ecosystem can be viewed as an energy flow system in which various species are connected by energy flows along food web links. To understand the co-evolution of the fast dynamics of energy flows and slow dynamics of food web structure, a simple reaction diffusion equation is presented in this paper. Some statistical indicators such as total system throughflow (TST) and Shannon entropy are designed...
