论文从影响喀斯特流域枯水径流的各影响因子入手，通过对入选流域的枯季前期降水量及其下垫面特征等16个因子的量化，从量上探求喀斯特流域的枯水径流各特征值与影响因子之间的相关规律。 | | 2. | The precipitation frequencies is analysed according to 1956 ~ 2000 years of rainfall record series in baoding area . the features of distribution of rainfall are detailed evaluated . firstly , the distribution of monthly precipitation is not even . for instance . the annual rainfall amount is about 548mm in whole year , about 80 % of them in summer season . secondly , yearly variation of rainfall is greater . thirdly , the abundant years usually are followed by short years , but the important changes have taken place in the last decades . before 70 ' s the abundant years took the dominant position , from the 70 ' s to the middle of 80 ' s the short years took place more frequently than ever . after the later of 80 ' s , the short years hold the main position . the above knowledge is instructive for guiding the rainwater resources effective utilization
本文利用1956 2000年保定市的长系列降雨资料，对保定市降水量进行了频率分析、年内变化分析和多年变化分析，明确了保定市降水量年内、年际间的变化情况：保定市降水量年内分配不均，汛期( 6 - 9月)占年降水量的81 。保定市降水量年际间变化大，丰水年和枯水年交替发生， 70年代以前以丰水年段为主； 70年代到80年代前期降水量丰枯交替频繁，总的接近于枯水年段； 80年代后期至今以枯水年段为主。这种降水分布规律对农业生产雨水资源的高效利用具有重要的指导意义。 | | 3. | The factors include antecedent precipitation of low flow period and status of karst basins ( such as lithology , landform , drainage area , drainage density , length and ratio of demotion of main river and so on . ) . based on the former studies , integrated the conventional statistic methods , the technique of anns is applied in this paper for researching the law of the low flow of karst basins in guizhou altiplano
影响喀斯特流域枯水径流的因素异常复杂，其影响因素主要有枯季前期降水量和岩性、地貌、流域面积、河网密度、主河道长度及其比降等流域下垫面状况。本文在前人研究的基础上，采用人工神经网络技术，结合传统的统计方法，研究贵州高原上喀斯特流域的枯水径流规律。 |
