The spatial and temporal characteristics and driving factors analysis of regional land use are the core scientific problems in the research of ecological environment and human sustainable development. It is also an important basis for the government to formulate land management policy. Based on the land use maps of 2000, 2005, 2010 and 2015, this article analyzed the spatiotemporal pattern of l...
Land cover has rapidly changed due to the relatively high population density, high rate of seasonal and permanent migrants, favorable conditions of natural and cultural, frequency of industrial units, coastal border and harbour and great rate of construction in the mazandaran province in recent years. Land cover changes are led to fragmentation, perforation, dissection, shirinkage, attrition an...
Abstract: Land-use and land-cover change research increasingly takes the form of integrated land-change science, the explicit joining of ecological, social, and information sciences. Traditional interdisciplinary methods are buttressed by new ones stemming from computational intelligence research and the complexity sciences. Several of these—genetic programming, cellular modeling, and agent-bas...
Land-use and land-cover change research increasingly takes the form of integrated land-change science, the explicit joining of ecological, social and information sciences. Traditional interdisciplinary methods are buttressed by new ones stemming from computational intelligence research and the complexity sciences. Several of these – genetic programming, cellular modeling and agent-based modelin...
This paper analyzes characteristics, major driving forces and alternative management measures of land-use change in Kunshan, Jiangsu province, China. The study used remote sensing (RS) maps and socio-economic data. Based on RS-derived maps, two change matrices were constructed for detecting land-use change between 1987 and 1994, and between 1994 and 2000 through pixel-to-pixel comparisons. The ...
Reducing land fragmentation can theoretically curb cropland abandonment, thus ensuring food security. However, few studies have quantified this relationship using large-scale survey data at the household level. This study adopts a two-way fixed-effects (TWFE) model to examine effect of on abandonment nationally representative panel from China Rural Household Panel Survey (CRHPS). The set contai...
