|
|
| Abstract: |
| It is an efficient approach that using the hollow grassland to increase rainfall infiltration and reduce the amount of water flow out during the rainy season. The ability to infittrote rainfall with different depth of hollow grassland in different hydrological years were analyzed and calculated. It is indicated that constructing hollow grassland is an efficient approach to increase rainfall use and protect or reduce flood disaster in cities. |
| Key words: hollow grassland,rainfall infiltration,infiltration effect |
