A Systematic Bibliometric Review of Low Impact Development Research Articles

The concept of low impact development (LID) plays a crucial role in rainstorm management and non-point source pollution prevention control. Sorting summarizing related research through the knowledge map can objectively present disciplinary structure, focus, hotspots LID research. Based on 2103 pieces literature Chinese English included web science (WOS) database China’s integrated resources system (CNKI) from 2004 to 2021, this paper aims perform statistical analysis three aspects: bibliometrics, keyword hotspot co-occurrence clustering, co-citation clustering. obtained results reveal that LID-based issues maintains high degree enthusiasm China abroad, but their corresponding focuses are dissimilar. Foreign essentially environmental field with frequent interdisciplinary phenomena, combining triple goals water quality improvement, runoff reduction, multi-functional expansion, is committed solving uncertain factors urban stormwater extreme climates. mostly aimed at unlocking practical engineering problems, which also leads majority works building engineering. This mainly due series water-related problems caused by change land use types China. researchers have determined type, quantity, location, combination optimal measures establishing appropriate models, using optimization algorithms, developing multi-level methods. Although multi-dimensional recent years greatly expanded framework paradigm, most conducted still biased towards micro-scale. considers how make macroscopic overall layout efficiently cooperate pipelines network, rivers, lakes systems unlock pertinent rainwater pollution.
