依据河口县的地形地貌特征，分东部、西部及中南部并采用定点监测、分级调查法对香蕉炭疽病的发生危害动态进行研究。结果表明：香蕉炭疽病在河口地区1～3月基本维持较低的危害水平，4月初开始发病，8～12月中旬处于危害的高峰值，12月份后逐渐下降；全年月平均危害率达38.44%，月平均危害指数0.81，处于危害率较高的水平；西部地区与东部、中南部地区的差异达到显著水平，月平均危害率西部地区(49.61%)＞中南部地区(35%)＞东部地区(30.72%)；不同海拔对香蕉炭疽病的田间发生危害有一定影响,但未达显著水平。

According to landform and physiognomy of Hekou county, occurrence and harm of the banana anthracnose were fixed-point monitored, classified and surveyed in east region, west region and middle south region. The results showed that harm of banana anthracnose maintained a lower level between January and March, occurred in the early April, kept in a high peak between August and middle December, and then reduced by degrees after December. Harm rate of banana anthracnose was very high all the year round. Its monthly mean harm rate is 38.44%. And its monthly mean disease index is 0.81. The difference of harm rate of banana anthracnose reached significance level among west region, east region and middle south region. Its monthly mean harm rate is 49.61% in west region, 35% in middle south and 30.72% in east region. The harm rate is influenced by different altitudes, but its difference doesn't reach significance level.
