从黑龙江省西部半干旱地区自然概况及河滩地经营现状出发。

According to the natural conditions and the management situation of the flood land of the west semi-arid Area of Heilongjiang province.

结果表明：混播可提高河滩地草场的产量，改善草层品质。

The results showed that mixed sowing grasses not only can raise the productivity but also can improve the pasture quality.

瘠薄河滩地整地质量的优劣，不仅影响林木的当年成活，而且还影响林木成活后的生长发育和连年生长量。

Site preparation quality in poor overflow land influences not only on survival rate of forest in the same year, but also on growth and annual increment after survival of forest.

利用野外移动式风洞试验装置，对永定河不同植被覆盖率河滩农地在不同风速下的风蚀量进行了测定，结果表明：播草盖沙可以提高起沙风速，有效减少河滩地的土壤流失。

It measures wind erosion under the conditions of different wind speed of floodplain area with different vegetation coverage ratio of the Yongding River by using mobile filed wind channel equipment.
