川东北小微湿地分布研究——以南充为例

Study on the Distribution of Small and Micro Wetlands in Nanchong

利用Bigemap GIS Office对南充市3区5县1市存在的小微湿地资源进行调查分析,结果表明,南充市小微湿地数量众多,其中小型水田湿地占小微湿地总面积的93.5%;不计水田,南充市小微湿地个数为33 191个,面积合计10 486 hm^(2),占南充市土地总面积的0.84%,其中面积小于1 hm^(2)的小微湿地个数为31 724个,占总数的95.6%;在计算水田的情况下,小微湿地面积为162 365 hm^(2),占南充市土地总面积的13.01%。

Bigemap GIS office was used to investigate and analyze the small and micro wetland resources in three districts,five counties and one city of Nanchong City.The results showed that there were many small and micro wetlands in Nanchong City,of which paddy field accounts for 93.5%of the total area of small and micro wetlands;excluding paddy fields,the number of small and micro wetlands in Nanchong City was 33191,with a total area of 10486 hm^(2),accounting for 0.84%of the total land area of Nanchong City,of which the number of small and micro wetlands with an area of less than 1 hm^(2) was 31724,accounting for 95.6%of the total.In the case of calculating paddy field,the area of small and micro wetland was 162365 hm^(2),accounting for 13.01%of the total land area of Nanchong City.
