Evaluating Ecological Vulnerability Using the GIS and Analytic Hierarchy Process (AHP) Method in Yan’an, China

The degraded ecosystem in the Loess Plateau region of China is very vulnerable, which has a great impact on regional sustainable development. Taking the Loess Plateau of Yan’an, Shaanxi province, China, as the study area, this study quantitatively evaluated conditions of the ecological environment. Based on natural factors, environmental factors, and socio-economic factors of Yan’an in 1997, 20...

Creating and Maintaining Topologies in Wireless Networks

Wireless ad-hoc networks differs in many aspects compared to traditional infrastructured networks. Among other things, individual nodes cannot be expected to know the topology of the entire network. Also, since nodes typically are powered by batteries and eventually will run out of energy, it is imperative for algorithms to minimize the energy cost while distributing it as fairly as possible ov...

Integrated Analytical Hierarchy Process (AHP) and GIS for Land Use Suitability Analysis

Analysis of land-use suitability requires consideration of variety of criteria. Application of GIS alone could not overcome the issue of inconsistency in expert opinion when trying to judge and assign relative importance to each of many criteria considered in a suitability analysis. To address this issue, the Analytical Hierarchy Process method is used in combination with the GIS tool. The pape...

Spatio-ecological complexity measures in GRASS GIS

24 Good estimates of ecosystem complexity are essential for a number 25 of ecological tasks: from biodiversity estimation, to forest structure 26 variable retrieval, to feature extraction by edge detection and genera27 tion of multifractal surface as neutral models for e.g. feature change 28 assessment. Hence, measuring ecological complexity over space be29 comes crucial in macroecology and geo...
