LIU Zi-qi, XIONG Kang-ning, Lü Xiao-xi, ZHANG Qian-zhu, FU Chao-fan
2015, 34(1): 43-51. doi: 10.11932/karst20150106
Abstract PDF(1836KB) icon1946 icon1371
Abstract:
By reviewing domestic and foreign research progress on the response of information of karst cave drip water to ground conditions, coupled with the research background of global climate change, karst environmental evolution and drip water's physical and chemical indicators, this paper divides the his...
Spatial-temporal distribution and causes of karst collapse in the Xuzhou area
WEI Yong-yao, SUN Shu-lin, HUANG Jing-jun, JIANG Su, MIAO Shi-xian
2015, 34(1): 52-57. doi: 10.11932/karst20150107
Abstract PDF(3400KB) icon2731 icon1723
Abstract:
Xuzhou is the only city in the Jiangsu Province to use the karst underground water as the municipal water. Due to the long-term absurd use of the Karst underground water, karst collapse often happens in the Xuzhou region. This paper looks into the distribution of bare karst and covered karst in the ...
