摘  要:菲律宾在恢复已消失的红树林方面做了大量工作,在过去的20年中尤为如此。鉴于此,评估这些工作的成果并把所获得的经验教训应用于目前的红树林管理便显得尤为重要。本文对几个有关评估菲律宾种植红树林的生长性能的研究项目的成果进行了综合分析。总的来说,一个普遍的趋势就是在非红树林自然生境的地方种植红树林,即把滩涂、砂坪、海草场改造成常常是由单一种类的红树属(Rhizophora)所构成的红树林。然而,在这些非红树林自然生境的地方,红树属树苗的死亡率很高。少数存活的红树属树苗(通常通过持续或多次种植)中,非自然生境和低潮间带生长的红树属幼苗个体生长缓慢;相比之下,自然生境和高潮间带生长的红树属幼苗个体生长繁茂。因此,本文认为红树林恢复过程中更合理的做法应是在红树林原来的生境,即半成水养殖池塘环境中重新种植红树林。同时,文中也探讨了相应的管理方案。当然,这些方案的最终实施与否取决于菲律宾国家和地方政府的政治意愿。The effort toward restoring lost mangroves in the Philippines has been commendably immense,specifically during the past two decades.In light of such,it is important to evaluate outcomes and,where appropriate,apply the lessons learned to the current strategies in mangrove forest management.This article synthesizes the results from several research projects assessing the performance of planted mangroves across the country.Overall,there is a widespread tendency to plant mangroves in areas that are not the natural habitat of mangroves,converting mudflats,sandflats,and seagrass meadows into often monospecific Rhizophora mangrove forests.In these nonmangrove areas,the Rhizophora seedlings experienced high mortality.Of the few that survived (often through persistent and redundant replanting),the young Rhizophora individuals planted in these nonmangrove and often low intertidal zones had dismally stunted growth relative to the corresponding growth performance of individuals thriving at the high intertidal position and natural mangrove sites.From this evidence, this article argues that a more rational focus of the restoration effort should be the replanting of mangroves in the brackish-water aquaculture pond environments,the original habitat of mangroves.For such,a number of management options can be explored,the implementation of which will ultimately depend on the political will of local and national governments.
