韶关市土地可持续利用评价研究

Study on sustainable land use evaluation in Shaoguan City

选择韶关市作为研究区域,利用遥感和GIS技术,构建了一套适合研究区域的土地可持续利用评价指标体系,并提出了一个土地可持续利用定量评价模型.然后对评价指标数据进行了标准化和空间化处理,对韶关市进行了基于栅格空间数据的土地可持续利用评价.最后总结了韶关市的土地可持续利用状况,提出适合研究区域土地可持续利用的可行性建议.

Let {^→X} be Markov Chains in random environments with countable State space. In this paper, first of all, we introduce Hopf Markov Chains and skew product Markov Chains. Further, we define φ- irreducibility On Markov Chains in random environments,its equivalence definition and main properties by skew product Markov Chains and the properties of ψ- irreducibility are obtained. Besides, we investigate the properties of support, closed sets, invariant measure and subinvariant measure in ψ - irreducibility.
