Objective:to study the epidemiologic characteristic of mortality of malignant tumors in zhongshan city.method:selecting the investigated datum of mortality of malignant tumor in zhongshan city as sample uses sas statistics software to analyse and forecast the mortality by time series.results:morlality of male malignant tumor and both male and female malignant tumour showed the risen trend from 1970 to 1989.the trend will be kept in future.both will be separately risen to 121.05/105 and 83.92/105 in 2 000.mortality of female malignant tumour will be kept in about 43.59/105 in 2000.couclusion:mortality of both male and female malignant tumor takes on the trend of diffirent change.the male showed risen trend;the female showed the fluctuation of non-trend random.rising mortality of malignant tumor greatly threaden the crowd health.

目的：研究中山市恶性肿瘤死亡率的流行学特点，为制定防治计划提供依据。方法：以中山市恶性肿瘤死亡率调查资料为样本，应用sas统计分析软件对恶性肿瘤死亡率进行时间序列分析与预测。结果：1970～1989年男性恶性肿瘤死亡率和男女合计恶性肿瘤死亡率均呈现上升趋势且有继续保持的趋势。到2000年将分别上升为121.05/10万和83.92/10万左右；女性恶性肿瘤死亡率呈现无趋势的随机波动且将继续保持下去，到2000年保持在43.59/10万左右。结论：中山市男女恶性肿瘤死亡率呈不同变化趋势，男性恶性肿瘤死亡率呈现上升的趋势，女性恶性肿瘤死亡率呈现无趋势的随机波动。恶性肿瘤死亡率的上升对人群的健康构成重大威胁。

The Markov forecast model, time series method (triple exponential smoothing method and a combined of triple exponential smoothing method and Markov model) and stepwise regression forecast method were choosed, and the basic principles and processes of the three models were analyzed and compared. Based on above, the three methods were used to predict population dynamic of Cricetulus barabansis and Meriones unguiculatus. The characteristic, accuracy and applicability of three methods were analysed and compared. The results showed that,(1) Markov model belongs to a middle-long time forecast model, and the result was interval forecast, but it reached the requirement of forecasting the harmful population dynamic of rodents. Through the forecasted population dynamic of Cricetulus barabansis and Meriones unguiculatus in 2004, the results were accurate; this meant that Markov model was a good forecast model to Cricetulus barabansis and Meriones unguiculatus population.

选择马尔可夫链预测模型、时间序列分析法(三次指数平滑法、三次指数平滑法和马尔可夫链预测模型的组合预测法)和逐步回归预测法，对这三种模型的基本原理、模型的构建过程进行对比分析，在此基础上用此三种方法预测了黑线仓鼠和长爪沙鼠的种群数量，并对三种方法的特点、预测的准确度和适用范围进行了比较分析，结果表明：(1)马尔可夫链预测模型属于中长期预测，预测的结果为区间预测，但对于害鼠种群数量的预测来说已经达到要求，通过对2004年黑线仓鼠和长爪沙鼠种群数量的预测，预测的结果都比较准确，这说明对于预测黑线仓鼠和长爪沙鼠种群的数量动态，马尔可夫链模型是比较好的模型。
