Research on Earthquake Landslides in Nielamu County Based on GIS

Hao Shu-feng et al（School of Engineering， Xizang University， Lhasa， Xizang 850011）

Abstract In this paper， nyalam county was taken as the research object， and the earthquake landslide in the research area was analyzed by analytic hierarchy process based on ArcGIS software， and six influencing factors， such as earthquake peak acceleration， rainfall， slope， aspect， relative height difference and vegetation coverage rate， were selected. By calculating the weight coefficient of each influence factor， the zoning map of predicted earthquake landslide in Nyalam County is drawn and interpreted， which revealed the distribution characteristics of earthquake landslide in Nyalam County， and provided a scientific basis for the relevant departments of disaster prevention and control in Nyalam County to improve their response ability.

Key words GIS; Earthquake landslide; Analytic hierarchy process

摘要 以聶拉木縣為研究對象，基于ArcGIS軟件運用層次分析法對聶拉木縣地震滑坡進行分析并選擇地震峰值加速度、降雨量、坡度、坡向、相對高差、植被覆蓋率6類影響因子，通過計算各影響因子的權(quán)重系數(shù)，繪制出聶拉木縣預(yù)測地震滑坡區(qū)劃圖并進行解譯，揭示了聶拉木縣地震滑坡的分布特征，為聶拉木縣災(zāi)害防治相關(guān)部門提高應(yīng)對能力提供科學(xué)依據(jù)。（剩余3238字）
