A comparison of three methods of multivariate analysis of upland grasslands in North Wales
In a study of the relationships between vegetation and environment in North Snowdonian grasslands, 166 quadrats on 10 altitudinal transects were analysed with Detrended Correspondence Analysis, Detrended Canonical Correspond- ence Analysis and Fuzzy Set Ordination. These techniques provide consistent results. DCCA and FSO, both using floris- tic community data and environmental information, simplify the procedure of vegetation-environment analysis. FSO analy- ses and synthesizes ecological information; it may yield more reasonable and interpretable results.
Abstract This paper describes the philosophy, algorithms, and implementation of a computer simulation model for land use forecasting, and the capability of generating maps of these forecasts. The model is applicable to SMSA's organized on a census tract basis by counties. The forecasts are macro to the census tract level for industrial, residential, commercial and public land uses. Modeling is based on an economic data base of the region, and is extremely flexible for the user. An example set of forecasts and maps is included for illustrative purposes.
