摘要

由于城市扩张和建筑和农业环境的增加而抑制了自然空间,影响了水资源质量,特别是在人口密度高的地区。考虑到巴西环境法律框架的进展,本研究旨在通过对巴西大都市地区的城郊流域的个案研究,核实土地利用是否仍然影响水质。采用方差分析和遗传规划相结合的方法,对不同季节、不同土地利用参数的多个样点的理化指标进行了分析。结果表明,城市与耐热大肠菌群(R = - 0.82, p < 0.01)、混合植被与溶解氧(R = 0.80, p < 0.001)、农业/牧场与生化需氧量(R = 0.40, p < 0.001)、甘蔗与浑浊度(R = 0.65, p < 0.001)对水质的时空影响具有显著的统计学意义。反过来,基因表达编程允许基于土地利用类型学解释水质参数变化的能力来计算其重要性。最后,尽管巴西法律取得了进展,但土地使用仍然对水质产生了重大影响。需要制定公共政策和决定,以确保有效遵守法律准则。

Spatiotemporal Effect of Land Use on Water Quality in a Peri-urban Watershed in a Brazilian Metropolitan Region: An Approach Considering GEP-Based Artificial Intelligence
The suppression of natural spaces due to urban sprawl and increases in built and agricultural environments has affected water resource quality, especially in areas with high population densities. Considering the advances in the Brazilian environmental legal framework, the present study aimed to verify whether land use has still affected water quality through a case study of a peri-urban watershed in a Brazilian metropolitan region. Analyses of physical–chemical indicators, collected at several sample points with various land-use parameters at different seasons of the year, were carried out based on an approach combining variance analysis and genetic programming. As a result, some statistically significant spatiotemporal effects on water quality associated with the land use, such as urban areas and thermotolerant coliform (R = − 0.82, p < 0.01), mixed vegetation and dissolved oxygen (R = 0.80, p < 0.001), agriculture/pasture and biochemical oxygen demand (R = 0.40, p < 0.001), and sugarcane and turbidity (R = 0.65, p < 0.001), were verified. In turn, gene expression programming allowed for the computing of the importance of land-use typologies based on their capability to explain the variances of the water quality parameter. In conclusion, in spite of the advances in the Brazilian law, land use has still significantly affected water quality. Public policies and decisions are required to ensure effective compliance with legal guidelines.
