| 中文摘要 | 石漠化是与北方荒漠化和黄土高原水土流失并列的中国三大土地退化问题之一。根据石漠化领域内的相关研究,系统总结了石漠化空间格局及动态过程研究、石漠化发展演化的机理研究等方面的进展与不足,提出构建基于中高分辨率遥感数据的石漠化时序轨迹新方法,并在此基础上进行长时间序列的石漠化过程分析,从时间和空间上定量、定位追踪石漠化的发展演化过程,不仅可以查明石漠化的发生地点及程度,还可以分析其发生和演化机理。将石漠化格局、过程与成因定量分析相结合,可以从更长的时间段内,更加精确地研究石漠化的时空变化规律,全面系统地揭示石漠化演化机制。 |
| 英文摘要 | Karst rocky desertification is the third severe land degradation in China, following desertification in the north and soil and water loss in the Loess Plateau. This paper reviewed the progress and problems in the studies of Karst rocky desertification, and proposed a new method, which is temporal trajectory analysis based on high-resolution remote sensing data. At present, we have achieved great progress in the fields such as karst geology and geomorphology, restoration and reconstruction of Karst ecosystem, spatial pattern and dynamic changes of rocky desertification, evolution mechanism of karst rocky desertification as well as monitoring methods based on remote sensing. However, there are still a number of problemsin the studies of evolutional process of karst rocky desertification: (1) Current studies are mainly focusing on the spatial pattern of the rocky desertification based on remote sensing data and have successfully described the degree of severity of land degradation, but few of them are concerning the evolutional process of karst rocky desertification; (2) Most of the studies on the evolutional mechanism of Karst rocky desertification are qualitative descriptions and few of them are quantitative analyses; (3) The remote sensing monitoring methods normally are the double temporal variation detection method based on the "two time cycle" scales; only the information of "change/no change" or "what changes from what" can be acquired. Therefore, a new method, temporal trajectory analysis based on middle/high resolution remote sensing data, is introduced in this paper. This methodfocuses on "continuous" variations in a long time scale, and it is concerning not only what has changed between two time points, but also "where" and "how" the changes happened. By the temporal trajectory analysis method, the rocky desertification process in a long time series can be investigated, and the development of rocky desertification can be quantitatively and spatiallytracked, so that we can know where, how and why the rocky desertification has happened. Temporal trajectory analysis method has advantages in discovering the evolutional process of rocky desertification. Moreover, quantitative analysis ofthe pattern, process and evolutional mechanism of Karst rocky desertification will be the trend in the future. |
