摘  要:
以我国北方湿地为研究对象,在统计分析沼泽植被盖度的基础上,分析了盖度对湿地实际腾发与潜在腾发之间关系的影响。结果表明,盖度最高为95%,最低为5%~10%。植被盖度在70%以上的沼泽占总沼泽数的75%;植被盖度在50%以下的沼泽只占总数的12%。在考虑盖度影响的情况下,实际腾发量大于当地潜在腾发量的沼泽占总数的82%;实际腾发量为潜在腾发量2倍以上的沼泽占总数的58%。

摘  要:
The effect of vegetation coverage on ETof swamp wetlands in northern of China was studied based on the analysis of vegetation coverage of swamps.The results showed that the top vegetation coverage was 95%,and the lowest was about 5%~10%.The swamps with coverage above 70% were 75% of the total swamps,and the swamps with coverage below 50% were only 12%of the total.Considering the vegetation coverage,actual ETthat was greater than the potential ET was 82% of the total the swamps;actual ETthat was 2times greater than the potential ET was 58% of the total swamps.
