Abstract

According to shallow groundwater, extensive distribution of lowland in the Four-lake Watershed and local practice in agricultural production, more than 50 mm of rainfall is regarded as a rainfall that possibly produce water-logging in cropland. Analysis showed that this kind of rainfall is characterized by the following: most of the rainfall emerged in the first ten days of May and in the last ten days of June, and averagely once every 2.6-2.9 years, the duration of the rainfall process was mostly within 7 days, mainly lasted for 3-5 days; in the area rainfall with precipitation from 50.1 to 100 mm usually results in subsurface water-logging in cropland, and occurs in the area 3.8 times a year, it may emerge from March to September, during which rainfall is quite frequent in May and June; rainfall more than 100 mm often causes surface water-logging in farmland, which mainly occurred in June, July and August, its frequency is 32.76%, 43.10% and 24.14% respectively; in rainy season, short interval (within 7 days) of the rainfall often results in Concomitance of Surface Water-logging and Subsurface Water-logging (CSWSW) which is very common in the Four-lake watershed and may occur from March to August, especially at the end of spring and the beginning of summer owing to the impact of the subtropical monsoon climate, generally, no less than 2 times CSWSW is highly frequent for winter wheat from jointing to mature period (Mar. to May), and for cotton at seedlings stage (May to mid-June) and in the period of cotton budding and bollsetting (mid-June to August), this will greatly affect crop growth.

使农田内涝的降雨特征
根据地下水较浅、四湖流域低地分布广泛以及当地农业生产实践,超过50毫米的降雨量被认为是可能导致农田内涝的降雨量。分析表明,该次降雨具有以下特点:降雨主要出现在5月上旬和6月下旬,平均每2.6 ~ 2.9年一次,降雨过程持续时间多在7天以内,主要持续3 ~ 5天;降雨量在50.1 ~ 100 mm之间的地区通常造成农田地下积水,该地区每年发生3.8次,3 ~ 9月出现,5、6月降雨较为频繁;大于100 mm的降水常引起农田地表内涝,主要发生在6月、7月和8月,发生频率分别为32.76%、43.10%和24.14%;雨季降雨间隔短(7天以内),往往造成地表和地下积水的同时发生,在四湖流域非常常见,发生时间为3 - 8月,特别是受亚热带季风气候的影响,在春末夏初,冬小麦拔节至成熟期(3 - 5月),地表和地下积水的发生频率一般不低于2次;在棉花苗期(5月至6月中旬)和棉花出芽结铃期(6月中旬至8月),对作物生长影响较大。
