In this paper, different land-use planning models have been reviewed; within this review, techniques and methodologies with different objectives, applications, and land uses have been identified. The existing literature in this field is dispersed throughout different subjects, such as planning, geographical information systems (GIS), decisionmaking, or computer systems. The compilation, analysis, and comparison of the different models have allowed us to draw a series of conclusions for the development and implementation of strategic plans for rural land use. Because GIS have become an essential tool in rural land-use planning, special attention has been paid to the models and methods integrated into GIS.
Resumo: Neste traballo analízanse os grandes cambios da paisaxe que tiveron lugar en Galicia nas dúas décadas posteriores á entrada de España na Comunidade Económica Europea, empregando mapas de usos da terra dos anos 1985 e 2005. Os resultados indican que durante este tempo aumentaron a superficie urbanizada e a de arborado e diminuíu a ocupada pola agricultura e a gandería, á vez que grandes áreas do territorio ficaron abandonadas. A comparación con datos da capacidade produtiva do solo revela que a urbanización e o mantemento do uso agrícola ou gandeiro tiveron lugar principalmente nas terras de maior calidade produtiva, mentres que a forestación se concentrou en terras de calidade intermedia e o abandono afectou ás de peores características. Unha análise de conglomerados a escala parroquial permitiu localizar as grandes áreas do territorio onde os cambios foron de distinta natureza, e coñecer como estas áreas están fortemente relacionadas coa altitude.Abstract: This paper focus on the changes in the landscape that took place in Galicia in the two decades that followed the access of Spain to the European Economic Community, using land use maps from 1985 and 2005. Results show that urban and forest areas increased during this period, while total area dedicated to agriculture and animal husbandry decreased and large portions of the whole territory were simply abandoned. The comparison with land capability maps revealed that urbanization and conservation of agricultural use mainly took place in the best soils, while afforestation was concentrated on intermediate soils, and abandonment was closely linked to the worst quality soils. A cluster analysis at parish scale allowed to identify different parts of the territory where different changes were dominant, and showed how these are largely correlated with altitude.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
