明清时期广东山区的陂塘水利与生态环境

Water Conservation Project and Ecological Environment in the Mountainous Areas of GuangDong Province in the Ming and Qing Dynasties

叙述了明清山区陂塘水利与生态环境之间的关系。陂塘水利改善了山区的农业环境,提高了土地的价值。而日益严重的水土流失使河道和陂塘淤塞,废弃的河道、陂圳、山塘又被占垦为田。同时,陂塘水利的发展与航运矛盾,减弱了陂塘水利的功能。溪流河道上层级而设的陂坝使径流流速减慢,沙泥停蓄。而河床渐高又使河水漫溢,也影响了对水力资源的运用。人们针对当时陂塘水利出现的情况,提出了一些治理的措施。

It is about the relationship between water Conservation project and ecological environment in the mountainous areas in Guangdong Province in the Ming and the Qing Dynasties.Water facilities improved ecological environment and the value of the land in the mountainous areas.But the growing soil erosion from mountains blocked the ponds and dams and raised the level of river bed.Waste ponds,river beds,and ditches were reclaimed into farmland.The previous dams of the rivers blocked shipping.The dams also slowed down the runoff flow,and caused mud stagnant.The increasing river bed and river overflow affected the shipping in the water resources.Controlling measures were proposed for silting ponds and increasing river beds.
