An analysis on driving force of land use change in Huajiang Demonstration Area of Guizhou

以我国典型的喀斯特脆弱生态区———贵州省花江示范区为例,在分析其土地利用动态变化特征的基础上,对影响花江示范区土地利用变化的驱动因子进行了定性分析和定量验证。结果表明,经济利益、人口增长、政策驱动、土地资源条件和价值观念取向是花江示范区土地利用变化的主要驱动力,并提出相应的措施,以尽可能避免土地向不利于可持续发展的方向变化。

The conclusion indicated that economic benefit, population growth, policy driving, land resource conditions and value concept tropism are the main driving forces of land use change in Huajiang Demonstration Area.
