摘要
根据1996—2009年辽宁省土地变更数据,运用土地利用结构信息熵分析了辽宁省土地利用结构的变化轨迹,研究发现辽宁省农用地呈下降趋势,建设用地呈上升趋势,其中耕地和牧草地下降趋势明显。在此基础上利用主成分分析法,对辽宁省土地利用结构变化的驱动因子进行了分析。研究发现对辽宁省土地利用结构起驱动作用的社会经济因子主要有人口因素、经济因素和城市化因素。根据分析结果,针对推动辽宁省土地利用结构合理化提出了相应的政策建议。
Based on the land change data of 1996--2009, this paper analyzes the evolution of land use structure in Liaoning Province by using the structure information entropy, and finds that in Liaoning Province the construction land is on the rise and the farmland is on the decline, with the cultivated land and grassland decreasing significantly. Then, the principal component analysis is applied to explore the driving factors of land use structure change in Liaoning Province. The findings indicate that the social-economic factors driving Liaoning＇s land use structure change mainly include population, economy and urbanization. Aiming at rationalizing the land use structure in Liaoning Province, some corresponding policy recommendations are finally made.
