Land-use change models are important tools for integrated environmental management. Through scenario analysis they can help
to identify near-future critical locations in the face of environmental change. A dynamic, spatially explicit, land-use change
model is presented for the regional scale: CLUE-S. The model is specifically developed for the analysis of land use in small
regions (e.g., a watershed or province) at a fine spatial resolution. The model structure is based on systems theory to allow
the integrated analysis of land-use change in relation to socio-economic and biophysical driving factors. The model explicitly
addresses the hierarchical organization of land use systems, spatial connectivity between locations and stability. Stability
is incorporated by a set of variables that define the relative elasticity of the actual land-use type to conversion. The user
can specify these settings based on expert knowledge or survey data. Two applications of the model in the Philippines and
Malaysia are used to illustrate the functioning of the model and its validation. 相似文献

This study has attempted to estimate the energy consumption and emission of pollutants namely carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx) and non-methane volatile organic compounds (NMVOC) from the road transport sector in Malaysia from the year 2012 till 2040. This was done using the long-range energy alternatives planning (LEAP) model. Estimates of energy consumption and emissions were evaluated and analysed under a business-as-usual scenario and three other alternative fuel policy scenarios of biodiesel vehicles (BIO), natural gas vehicles (NGV) and hybrid electric vehicles (HEV). The aim of this study has been to identify the potential alternative fuel policies that would be effective in reducing the future growth of road transport energy consumption and emission in Malaysia. Results indicate that the NGV scenario contributes towards the highest reduction in road transport energy consumption followed by BIO and HEV. The NGV scenario also achieves highest mitigation of emission of all the four pollutants. In the case of CO2 emission, BIO scenario attains second highest mitigation, whereas in the event of CO, NOx and NMVOC emission, HEV scenario achieves second highest mitigation. 相似文献
