基于遥感的渝东南喀斯特石漠化特征分区及其治理模式实证研究——以重庆市酉阳为例

以重庆市酉阳县为例，在地理信息系统和遥感技术的支持下，结合野外调查，分析石漠化分布现状和驱动因子，并利用GIS分析功能，进行多要素空间组合分析，实现了对信息的深挖掘，揭示了石漠化的空间分布规律，并根据自然环境条件、社会经济条件和石漠化程度的不同进行石漠化治理分区研究，因地制宜地采取不同的有针对性的治理措施和模式．坡改梯、退耕还林、特色经营果林建设、农田基本建设、生态修复等是喀斯特石漠化治理的有效模式．

Empirical Research on Classification and Control Modes of KarstRocky Desertification Zone in Southeastern Chongqing Based on Remote Sensing——A Case Study of Youyang in Chongqing

This article taking the County of Chongqing Youyang as an example, supported by geographical information system and remote sensing technology, and combining field investigation, analyze, current distribution of KarstRocky desertification and its driving. Using GIS analysis function it carries on the multi-essential factors space combination analysis, and has realized to the information deep excavation, and effectively promulgates the KarstRocky Desertification spatial distribution rule. We carries on KarstRocky desertification control according to natural environment terms , social economic terms and KarstRocky desertification difference of intensity dividing into area study, and take different pointed administration measures and modes in line with the local conditions. The slope changes to ladder, takes back from agriculture to the forest, constructs eccomomic and fruit-beating forest, conducts farmland capital construction, and ecology repair are dleffective KarstRocky desertification control patterns.
