Urban land use change may influence natural phenomena and ecological processes. Decreasing of cultivated land area in Chengdu is one of the critical problems in recent years. The objective of this study is to detect land use changes between 1992 to 2008 using satellite images of Landsat TM/ETM+. The land use maps of 1992 waw collected from 1:50000 digital maps and Arc/View 3.2 software. TM/ETM+ satellite...
Based on the Takens' delay-coordinate phase reconstruct, A third-order Volterra filter which is used to detect weak target signal in chaos is researched. A large class of Nonlinear systems have been successfully modeled using Volterra series techniques. The key to system modeling by means of a Volterra series is capturing the Volterra kernels that represent the system. Once the kernels are known,...
With the development of society and economy, the rapid urban sprawl in land use is being witnessed of late in urban districts. As a result, many problems in society and environment have appeared in urban districts, such as population expansion, air pollution, etc. Assessment and inventory on urban sprawl is essential for city planning and sustainable development. The objective of this study was to...
Because of the development of social economy, attentions have been given to human settlements. And the distribution of geographic population is determined by the natural suitability and the restriction of human settlements. Due to most researches focus on evaluation studies of urban human environment and deficiency of research methods chiefly composed by qualitative methods, this paper mainly adopts...
