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%。
The effect of vegetation coverage on ET of swamp wetlands in northern of China was studied based on the analysis of age was 95G, and the 1 the total swamps, and t vegetation actual ET coverage, act vegetation cover owest was about he swamps with ual ET that was that was 2 times greater than age of swamps. The results showed that the top vegetation cover 5%-10%. The swamps with coverage above 70% were 75% of coverage below 50G were only 12% of the total. Considering the greater than the potential ET was 82% of the total the swamps the potential ET was 58% of the total swamps.
