河北省邢台市土地生态安全评价及可持续发展对策研究

Assessment on Land Ecological Security and Sustainable Development Countermeasures in Xingtai City of Hebei Province

在对土地生态安全概念研究的基础上,以河北省邢台市为例,运用层次分析原理和土地生态安全模型,建立了适合该区的由22项指标组成的土地生态安全评价指标体系,对该区2000,2004和2010年的土地生态综合安全值进行了计算。研究结果显示,邢台市土地生态综合安全状况在2000年属于"敏感级",在2004年属于"风险级",在2010年属于"敏感级",均处于"不安全"状态。人口增长过快,土地污染,滥垦,滥伐,过度放牧以及粗放经营的生产方式是导致该市土地资源"不安全"状况的主要原因。最后提出确保土地生态安全的对策建议。

Based on clarifying of land ecological security and taking Xingtai City, Hebei Province as the case, using the principle of systematic analysis and the security matrix of land ecology, a system of 22 indexes suit- able for this region was used to calculate the status of three years（2000, 2004 and 2010 respectively）. The results show that the comprehensive security status of land ecology is labeled ＂sensitive grade＂ for 2000, ＂alarming grade＂ for 2004 and ＂sensitive grade＂ for 2010. It indicates that the land security status in Xingtai City in 2000, 2004 and 2010 is in the ＂unsafe＂ state. The main causes for the ＂unsafe＂ state are the popula- tion booming, land contamination, overgrazing, deforestation, overgrazing and extensive farming. Finally, this paper brings forward countermeasures to guarantee the safety of land ecology.
