Morphology and Developmental Mode of Blowouts in Hulun Buir Sandy Grassland, China 呼伦贝尔沙质草原风蚀坑形态发育模式分析
Protection of grassland vegetation and top soil layer is vital to avoiding the development of blowouts. 保护沙质草原区植被和地表土层不受破坏是防止风蚀坑发生发展的关键。
Previous study found that blowouts will evolve into wind-accumulated landform, such as parabolic dunes or linear dunes. However, blowout in this area can evolve into other types of wind eroded landforms. 前人的研究发现风蚀坑多发展为风沙堆积地貌,例如抛物线型沙丘或线性沙丘,而本区风蚀坑则可发展为其他类型的风蚀地貌。
This is because, once the blowouts occurred, it will cause not only huge property losses, but also environmental pollutions and even the casualties. 因为,井喷事故一旦发生,不单单造成巨大的财产损失,还会造成环境污染甚至人员的伤亡。
The primary function of this system is to collect and process the data, transfer and display the data on the LED screen, communicate with the host, and send the alert signal before the blowouts. 它的主要功能是完成数据采集、处理,将数据传送到LED屏上显示,与上位机通信并在井喷前发出报警信息。
