摘要
将中国南方生态系统的酸沉降敏感性等级与用MAGIC模型在对应样点计算的临界负荷值相结合,对中国南方生态系统的酸沉降临界负荷进行了研究,并编制了1°×1°经纬度网格的临界负荷图.研究结果表明,中国南方生态系统硫沉降临界负荷大多在2.3~5.2g/m2a之间,在地域分布上由东南向西北逐渐增大,其中临界负荷小于3.0g/m2a的极敏感地区为浙江南部、广东与福建交界地区、贵州西南部和广西中部.
The critical loads of acid deposition for
ecosystems in South China are studied by combining ecosystem sensitivity with site specific
studies, which are done using MAGIC model. A critical load map of acid deposition for
ecosystems in South China with a resolution of 1°×1° is produced. The result showed that
the critical loads of sulfur for ecosystems in South China vary from 2.3~5.2 g/m 2a and
increase from the southeast to the northwest on the whole. The four most sensitive areas where
the critical loads are less than 3.0 g/m 2a are the south of Zhejiang Province, the areas
between Fujian and Guangdong Provinces, the southwest part of Guizhou Province and the
central part of Guangxi Zhuang Autonomous Region.
