| Abstract: | Taking 8 major natural hazards as objects of oppraisal, adopting proper indexes and index weight,we have calculated the synthetic values and assessed the major natural hazards in 87 counties and districts in Gansu province. Further analyses are made on the space differentiation and sources of major hazards, thus providing a solid basis for regional disaster prevention and economic development. |
