This paper employs the chimp optimization algorithm (ChOA) to enhance the traditional random forest model, resulting in the chimp optimization algorithm\u2010random forest (ChOA\u2010RF) water quality assessment model for evaluating the Jiansanjiang area in Heilongjiang Province, China. The results show that the overall water environment in Jiansanjiang has the following characteristics: \u201cThe water quality of farms in the northwest is poor, and the quality of groundwater is better than that of surface water.\u201d Total nitrogen (TN) and total phosphorus (TP) in surface water and ammonium nitrogen (NH<jats:sub>3<\/jats:sub>\u2010N), ferrum (Fe), and manganese (Mn) in groundwater are the main pollutants. The TP and TN in surface water and the NH<jats:sub>3<\/jats:sub>\u2010N in groundwater exceeded the relevant standards, likely due to the excessive application of chemical fertilizers, especially nitrogen fertilizers. Additionally, Fe and Mn are harmful native substances. According to these findings, targeted improvement strategies, such as reducing nitrogen fertilizer application, plugging well, and increasing the surface water utilization rate, are proposed. Moreover, the ChOA\u2010RF model is compared with the traditional empirical value model and the particle swarm optimization\u2010random forest (PSO\u2010RF) model. The results show that the ChOA\u2010RF model can effectively reduce the root mean square error and mean absolute percentage error and improve the coefficient of determination. The running time and convergence ability are also better than those of the PSO\u2010RF model, which is a more accurate and efficient machine learning model. The model can be used not only for high\u2010precision evaluation of regional water environment quality but also for other machine learning fields.<\/jats:p>","DOI":"10.1002\/jeq2.20609","type":"journal-article","created":{"date-parts":[[2024,8,6]],"date-time":"2024-08-06T02:19:28Z","timestamp":1722910768000},"page":"604-617","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Regional quality analysis of the hydrological environment with an improved random forest model based on the chimpanzee algorithm"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-4449-5679","authenticated-orcid":false,"given":"Xuesong","family":"Li","sequence":"first","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Agricultural &amp; Rural Pollution Abatement and Environmental Safety, College of Natural Resources and Environment South China Agricultural University  Guangzhou China"},{"name":"Henry Fork School of Biology and Agriculture Shaoguan University  Shaoguan China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liangliang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Water Conservancy &amp; Civil Engineering Northeast Agricultural University  Harbin China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xian","family":"Chen","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Agricultural &amp; Rural Pollution Abatement and Environmental Safety, College of Natural Resources and Environment South China Agricultural University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifan","family":"Yang","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Agricultural &amp; Rural Pollution Abatement and Environmental Safety, College of Natural Resources and Environment South China Agricultural University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyun","family":"Mao","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Agricultural &amp; Rural Pollution Abatement and Environmental Safety, College of Natural Resources and Environment South China Agricultural University  Guangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,8,5]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jwpe.2024.104789"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/s20205763"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.still.2023.105777"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.marpolbul.2023.114618"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1010933404324"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gexplo.2023.107195"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.catena.2017.05.034"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11069\u2010021\u201004601\u20103"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2022.117488"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10661\u2010022\u201010742\u20100"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.3390\/w13213094"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.renene.2017.11.011"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cosust.2018.10.003"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.3390\/su10093006"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.patrec.2010.03.014"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclepro.2022.131847"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.renene.2021.07.120"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11042\u2010024\u201018137\u20108"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/agj2.20772"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvrad.2022.106843"},{"key":"e_1_2_10_22_1","first-page":"392","volume-title":"Groundwater geochemistry: Pollution and remediation methods","author":"Jaydhar A.
