| 中文摘要 | 研究目的:探讨喀斯特地貌发育典型的乌江下游德江县石漠化现状格局,为分类分步推进德江县喀斯特土地石漠化治理并采取相应的治理方案提供依据.研究方法:野外调研和GIS处理.研究结果:分析了德江县石漠化等级类型,并探讨了德江县土地石漠化现状与分区格局,提出了土地石漠化防治的4种主要模式及相应的措施.研究结论:德江县石漠化严重,全县土地石漠化面积为706.93 km~2,占全县土地总面积的34.1%,其中轻度、中度、强度、极强度石漠化面积分别占全县土地总面积的17.5%、11.4%、4.0%、1.2%,为遏止石漠化扩张,应尽快开展石漠化治理. |
| 英文摘要 | The purpose of this paper is to explore the present situation and distributing features of Karst rocky desertification in Dejiang County which is located at the lower reaches of WuJiang where karst landforms are widely distributed and typical,and it will provide scientific basis for improving the harnessing Karst rocky desertification in DeJiang County and adopting corresponding treatment plans step by step.The study methods employed: field investigation and GIS treatment.The study reveals that: analyzed the grade type of rocky desertification in Dejiang County and explored the present situation and distributing features of rocky desertification in Dejiang County,and put forward four main models for controlling rocky desertification and corresponding countermeasures.It is concluded that the rocky desertification in Dejiang County was very serious: the total area of rocky desertification is 706.93 km~2(accounting for 34.1% of the total land area of Dejiang county),and among them,the rocky desertification area of light degree,middle degree,serious and extremly serious degree accounts for 17.5%,11.4%,4.0% and 1.2% of the total area of Dejiang county respectively.Some corresponding countermeasures for controlling rocky desertification should be carried out as soon as possible in order to stop the expansion of the rocky desertification. |
