The Ai River is 15 kilometers long, of which 10.5 kilometers flow through Kaohsiung City. To prevent floods, long ago the city government put up tall dikes on both banks. These upright, steep dikes not only cut people off from access to the river, they also stifle plant growth along the banks, adversely affecting the ecology.
愛河流域全長十五公里，其中有十．五公里流經高雄市，當年為了防洪，政府在河堤兩岸高高築起堤防，這些垂直陡峭的堤防不但阻止了民眾親近愛河的機會，也讓兩岸草木無法攀沿生長，影響了愛河的生態。
