Land use change influences deeply on not only the structure and type but also the levelof the regional natural disaster. The paper takes Wulanchabu League of Inner Mongolia in China as anexample, which is situated in the middle of northern farming-pastural region and is affected deeply bynatural hazard. Based on the statistical data and field survey, the mechanism that grain crop yield isincreasing while the climate shows a fluctuation with drought tendency is presented. The main resultsshow as fellows.1 Tw as fellows.ence of land use change on agricultural natural disaster is to change relatively theagricultural vulnerability for natural hazard.2 The research on the example of Wu League shows that the increasing ability to fight disaster of theagricultural production displays chiefly the increasing of per unit area yield. But the grain yield is affected deeply by regional physical geography. To increase regional capability of disater reduction is keystrategy of ecological security construction.3 In the semi-arid region, the increasing the cultivated area proportion of the drought-resistant andhigh-yield grain contributes to reducing the vulnerability of grain production system. The change ofland use structure is an effective and feasible mitigation measure.
