一、里下河地区气候的基本特征苏北里下河地区位于苏北的中部,主体部分为兴化县和建湖县。里下河地区地形的主要特色是地势低洼,称之为江苏的“锅底”。如图1所示,在兴化、建湖和宝应三县城的中间为射阳湖,其面积与洪泽湖相当,东西跨度约有50公里,南北长度有60公里。但它不是一个完全水体的湖,而是一个沼泽地,在这一沼泽地里小的湖荡河叉交错,过去多为芦苇覆盖,近些年来已部分地改造为粮田。 First, the basic characteristics of the Lixiahe region climate Lubei area Lubei area is located in northern Jiangsu Province, the main part of Xinghua County and Jianhu County. The main feature of the Lixiahe area terrain is the low lying, called “pot bottom.” Shown in Figure 1, Xinghua, Jianhu and Baoying three counties in the middle of Sheyang Lake, its area and considerable Hongze Lake, east-west span of about 50 km, 60 km north-south length. But it is not a lake full of water, but a marshy area where small lakes and brooks staggered in the marshes and used to be mostly covered by reeds. In recent years they have been partly converted into grain fields.
