香港岛地区滑坡灾害的时空分布模式

香港岛是香港特别行政区开发程度最高的区域，人工滑坡及自然滑坡时常发生。滑坡灾害在时间和空间的分布受多种因素的影响并呈现出一定的规律性，本文利用GEO发布的近十多年的滑坡资料对香港岛地区滑坡灾害的时间、空间和时空分布模式进行了分析。

Temporal and Spatial Distribution Patterns of Landslides in Hong Kong Island

Hong Kong Island, with its area 77.1 km 2, is one landslide accumulated centre in Hong Kong Special Administrate Region. The climate of Hong Kong island is tropical and monsoonal, with hot, humid summers. The mean annual rainfall is about 2300mm and occasionally intense during thunderstorms and typhoons. Hundreds of landslides that most of them be classified as debris flow occurred every year. To study temporal and spatial distribution of slopes failure, the author analyze the landslides information reported and published by Geotechnical Engineering Office of Hong Kong from 1984 to 1996, and draw some conclusion as: (1) most landslides located on high development area; (2)distribution of large landslides corrected to geological element such as faults; (3) most reported landslides distributed near resident area where there are lots of man_made slope, cut_slope, fill_slope around. According conditions similarity rules, some slope failure will transfer to new development area controlled by Hong Kong government.
