“…As has been known, in recent years, Jakarta experienced an annual flood. Some studies indicate that the incidence of floods in Jakarta is closely associated with the destruction of forests in the upstream watershed (Costa et al, 2015;Lin et al, 2015). In this context, planning for land utilization for agriculture should respect the existing official spatial land use plan.…”

“…Scientific studies of subsidence have focused primarily on the biophysical indicators, methods and metrics of subsidence. They have tended to search for quantifiable metrics for issues such as urbanization (see Lin et al , ; Remondi et al , ) and have conflated some of the factors contributing to flooding (see Ward et al , ). But few studies have so far critically probed the associated social and political factors.…”

“…The three activities have different targets: the dredging of riverbeds is to reduce the sediments and waste in the river (Fig. 1); the installation of sheet piles is to strengthen the river walls and limit access to the river; unregulated settlements are evicted to increase the width of the channel to about 35 ~ 50 meters wide [27] [28] . Although riverbed dredging is not new in Jakarta, Normalisasi provides mechanized tools for increasing the speed of dredging, introducing dredging as one of the strategies of the package, and ensuring continuous funding for the entire program [29] .…”

“…2 "河流正常化"政策--雅加达市的防洪举措 早在1872年,雅加达的洪涝问题就已非常严峻。当降雨量达到 286mm时,河水便会泛滥,继而引发洪涝灾害。此后,1977年、1994 年、1996年、1999年、2002年、2007年、2013年先后发生多起重大洪涝 灾害事件,最近一次发生于2015年 [25] ,此次洪涝灾害导致5人丧生、约 23万人撤离,财产损失高达1.5万亿印度尼西亚卢比(约合1亿美元)。 为此,雅加达政府实行了多项举措,其中最新且最引人瞩目的即 为"河流正常化"政策。该政策全称"吉利翁河正常化项目",旨在 通过提升河流(尤其是吉利翁河)的泄洪能力来解决雅加达的洪涝问 题 [26] ,具体举措包括疏浚河床、安装板桩及取缔河流沿岸的非正规居住 点 [27] 。疏浚河床的目的是减少河道中的淤积物(图1);安装板桩则是 为了加固河堤,并限制人们接近河流;取缔河流沿岸的非正规居住点 则意在将河道拓宽至35~50m [27] [28] 。尽管河床疏浚对于雅加达而言并非 创新之举,但"河流正常化"政策引入了可大大提高疏浚效率的机械 化工具,将机械化疏浚纳入项目策略制定之中,以确保整个项目稳定 的经费来源 [29] 。 截至2017年,全长33.69km的吉利翁河中已有16.38km的河段实施 了"正常化"政策 [27] 。尽管周边居民表示洪水致灾的频率有所降低,但 由于近期河道内的水量已与河堤持平,他们仍然担心河水再次泛滥 [27] [30] 。此外,被迁出的居民对新住处的安置条件也存在顾虑。已有部分迁 移居民对政府提供的公寓表示不满,其中地段偏远和租金过高是主要 原因 [31] 。近来,由于公众反对声音较大,雅加达政府已叫停非正规居住 点居民的迁移,"河流正常化"项目因此搁置 [32] 目前有学者对"河流正常化"政策的技术官僚性进行了批判 [26][35] , 指出该计划更长远的目标可能是进一步吸引基础设施建设投资,进而带 动经济增长,但不应以牺牲包容性城市景观为代价,因为这将导致沿河 居民的边缘化。尽管雅加达的土地淹没问题有所缓解 [36] (图2),但地 面沉降的加剧(图3)可能进一步削弱城市应对洪涝灾害的能力 [15][16] 。 这座城市的地面沉降与洪涝问题之间有着千丝万缕的联系,需进一步探 究。此外,受气候变化影响,雅加达的降雨模式也可能发生改变 [34] ,因 此需提高整座城市的水管理韧性,以应对未来的风险 [24] 。 本文采用系统动力学方法 [37] 来探究雅加达城市发展与水文-地貌 之间的动态复杂关系,深入分析了城市防洪减灾能力不足的原因,同 时就雅加达面临的现有挑战和未来风险评估了当前的"河流正常化"…”
