| 摘 要： | 在收集利用已有资料的基础上,基于2014年土地年度变更调查国产高分卫星数据,采用"3S"技术,大面积快速调查和监测石漠化位置、面积、等级,分析研究其时空分布与变化规律。为政府部门和专业部门提供决策依据。调查结果表明,湖南省2014年石漠化面积3125.24 km~2,2007~2014年7年间总体上呈减少趋势,但是,中度石漠化面积仍有所增加。湘西地区和沅江流域石漠化分布面积较大。

| Abstract: | Based on the available data and based on the data of domestic high-resolution satellite about the annual land-use change survey in 2014, and using the "3S" technology to rapidly investigate and monitor the location, area and grade of rocky desertiifcation in large area, analysis and study of its spatial and temporal distribution and variation law,which provide the basis for decision-making for the government departments and professional departments.The results show that the area of rocky desertiifcation in Hunan province is 3125.24 km2 in 2014, and the overall trend was decreased in the 7 years from 2007 to 2014. But the area of moderate rocky desertiifcation is still increasing. The distribution area of rocky desertiifcation is relatively large in Xiangxi and Yuanjiang watersheds. |
