Abstract: | Corridors are special patches with narrow and long shape, and often have the functions as transportation,protection, resources and aesthetics. Corridors in the study area can be classilied into 8 types, with a total length of 5167. 2 km, and conidor density of 1. 25 km/km2. The conidore are mainly composed of irrigation and drainag canals,the total length of which is 2794 km,about 54. 1% of all the corridors. The conidors have segmented the landscape, and changed the original situation of the natural landscapes. The types of conidors are clooely related to the landscape types they are distributed in. Canals are maily distributed in the wetland landscapes, while roads are mainly in the built-up area. Dikes are always along rivers or coastlines. The conidors are most densely distributed wherever human activity occurs most bouendy, such as in the artifical wedlands of paddy fields. |
