The authors discuss the main distribution of slip and fall in China and harm and reason analysis,put forward the measures of protection and control of geological disasters,in the hope that the protection of geological environment can become an important part of the process of the social development .

Monitoring during construction of prevention works for landslides and the effect analysis;

Areal landslides susceptibility analysis——A case study in Hong County, Sichuan Province;

In this paper,thewriter studies the regularities governing the density of collapse and landslide on the upperMing Jiang River Basin.

Then using sensitivity coefficient analyzed the sensitivity of collapse and landslide to stratum lithology in research area,according to research area actual situation,the sensitivity coefficient is divided into four ranks which extremely sensitive area accounts for 29.
