科尔沁沙地沙漠化研究进展

Advances in desertification research of Horqin sandy land

科尔沁沙地是目前我国沙漠化发展较为迅速的地区之一,也是我国沙漠化研究程度比较高的地区之一。近50年来,该区沙漠化研究经历了流沙治理、沙漠化过程及其整治的区域性综合研究和沙漠化机理及其整治的典型研究3个阶段,在沙漠化过程、动态监测、灾害评估、综合整治防治等方面都取得了大量成果。根据目前的研究现状和存在问题,以及科尔沁沙地的实际情况,提出了今后应进一步加强研究的4个领域,即:沙漠化监测评估标准的统一和规范化;农田土壤风蚀的实验观测和控制措施的试验示范研究;沙尘暴灾害的监测、预警和影响评估;防沙治沙技术与模式的集成和进一步推广等。

Horqin sandy land is one of the regions expanded quickly and researched extensively in desertification in China. In past five decades, the desertification research of Horqin sandy land went through three stages: control of shifting sand dune, regionally integrated study of desertification processes, and demonstrative study on control of desertification. A lot of achievements have been made in the processes, dynamic monitoring, and disaster assessing and integrated management of desertification. According to the status quo of research, existent problems and actual situation of Horqin sandy land, the four aspects below need be further studied: the unification and standardization of monitoring and assessing standard of desertification; the experimentation and demonstrative research of the field observation and control measures of soil erosion in farmland; the monitoring, warning and influence assessment of dust storm disaster; the integration and further popularization of the techniques and modes of prevention and control.
