清代江南海塘防护植物的种类与分布 ,是自然选择、社会与人为因素综合作用的结果。经济利益驱使部分塘长和近海居民 ,违禁种植某些对海塘防护不利的植物 ,这对白蚁的穴居有利。狗獾在海塘上的穴居时间和海塘的岁修日期、风暴潮之间不同步 ,使其对海塘的破坏持久存在。白蚁的强力破坏和海塘取土之间的矛盾 ,说明了海塘防护中的两难选择。燃料问题 ,增加了对海塘及其防护植物管理的难度。植物、动物和人之间的联系 ,表明清代江南海塘的防护是个生态互动的复杂问题 The species and distribution of protective plants in the seashore of Jiangnan in the Qing Dynasty are the result of a combination of natural selection, social and human factors. Economic benefits drove some of the pond managers and offshore residents to ban the cultivation of certain plants that are detrimental to seawall protection, which is beneficial to the habitat of termites. The time between the cavers’ death on the seawall and the sewer’s senescence and storm surge are not synchronized, leaving their destruction of the seawall persistent. The contradiction between the termites’ destructive power and seabed borrowing shows the dilemma of seawall protection. The fuel problem has added to the difficulty of managing seawalls and their protective plants. The connection between plant, animal and human indicates that the protection of Jiangnan sea-pond in Qing Dynasty is a complicated issue of ecological interaction
