    宫德吉 郝慕玲 侯琼
    1996, 22(10):3-7. DOI: 10.7519/j.issn.1000-0526.1996.10.001

    The mainly factors of the drought causing disaster are analysed. The results show that the drought disaster occurring mostly depends on the states of the crop water requirement and the environment water supply. The precipitation variability,the water store in soil layers,the crop response on rainfall deficit in the different growing period and activity influence on the drought disaster. Because the crop sensibility to water in the growing periods are different, the complex evaluation is conducted according to the rainfall deficit, the deficient duration and the crop sensibility to water during the deficient rainfall. The complex index evaluating the drought disaster is also given.

    The subject is to study an example of special sandstorm occurred in Gansu province viith recursive similarity. The jump was defined as the level that the preceding numbers of R data could not completely describe the present state. The results indicated that every element violent wave at 16 o'clock was not the larger jump value in recursive similarity,the larger values were occurred before 16 o'clock. At last,The formal abrupt and essential abrupt were presented.
