本文对上海浦东东海海滩上［３１°１＇Ｎ］芦苇植被自堤至海水边各地段的生物生产力、生长特性及土壤状况作了测定。其平均生物生产力为２．０７４±０．５５４ｋｇｍ￣（－２）ａ￣（－１），其中地上部和地下部生物量分别为１．４３３±０．３８２和０．６４１±０．５６６ｋｇｍ￣（－２）ａ￣（－１）。观察了自芦苇出土起，大气ＣＯ＿２浓度加倍对芦苇生长的影响。结果表明，处理４４ｄ后植株叶面积和比叶重相应提高，生物生产力比对照增加５３．７％，其光合产物主要分配在地上部分。试验结束时，ＣＯ＿２加浓处理的叶片叶绿素含量和在正常空气中的光合速率与对照相似。
In this paper, the biological productivity, growth characteristics and soil conditions of [31 ° 1’N] reed vegetation on the East China Sea beach in Pudong, Shanghai were measured. The average bioavailability was 2.074 ± 0.554 kgm ~ (-2) a ~ (-1), and the above and belowground biomass was 1.433 ± 0.382 and 0.641 ± 0.566kgm ~ (-2) a ~ (-1). The effects of atmospheric CO 2 concentration on the growth of Phragmites australis were observed since the reeds were unearthed. The results showed that the leaf area and specific leaf weight increased after 44 days and the biological productivity increased 53.7% compared with the control. The photosynthate was mainly distributed in the aerial part. At the end of the experiment, the leaf chlorophyll content and the photosynthetic rate in normal air were similar to those of the control.
