Slope is a critical factor influencing nitrogen removal, as it regulates flow velocity and hydraulic retention time, both of which govern nutrient transport and biogeochemical reaction. Despite this importance, the effects of slope on nitrogen removal performance in drainage ditches remain insufficiently investigated. In this study, three types of ecological drainage ditches—concrete-pier porous-brick (ED1), vegetated porous-brick (ED2), and sod-lined gravel–sand–soil ditches (ED3)—were evaluated, with a conventional concrete ditch (CD) serving as a control. Field scouring experiments were conducted under three slope gradients (1°, 5°, and 9°), representing gentle, moderate, and steep conditions, with two flow rates (70 and 140 L·min⁻¹) applied to assess nitrogen removal efficiency under different hydraulic regimes. Results showed that slope markedly affected TN removal efficiency, with distinct responses across ditch types. ED2 was the most sensitive to slope changes, with its TN removal efficiency decreasing by 15.8 % as slope increased from 1° to 9°. In comparison, TN removal efficiency declined by 14.0 % in ED3 and by only 3.7 % in ED1. Notably, ED3 maintained relatively stable TN removal efficiency across slope gradients while sustaining a high overall level of removal. Functional priorities of ditches varied with slope conditions: gentle slopes favored nutrient removal, moderate slopes necessitated a balance between water conveyance and nutrient removal, and steep slopes emphasized water conveyance supplemented by localized ecological interventions. These findings underscore the importance of aligning ditch types with slope conditions, thereby optimizing ecological engineering strategies for agricultural non-point source pollution control and improving regional water quality to support agricultural sustainability.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"224 ","pages":"Article 107888"},"PeriodicalIF":4.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145837194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Qinghai Province, situated on the Qinghai-Tibet Plateau, was divided into five ecological plates: the Three-River-Source, Qaidam Basin, Qilian Mountains, Pan-Gonghe Basin, and Hehuang Valley. Based on exploratory spatial data analysis, we first assessed the supply and demand of EPs from 2000 to 2020, encompassing food production (FP), water conservation (WC), carbon sequestration (CS), soil retention (SR), and outdoor recreation (OR). Then, we constructed the ecological products supply-demand index (EPSDI) and analyzed its spatiotemporal matching and agglomeration characteristics. Finally, we revealed the spatiotemporal evolutionary differences in EPs supply and demand across different ecological plates. The results indicated that (1) Both the supply and demand of EPs showed an upward trend, with their spatial distribution exhibiting a pattern of being higher in the east and lower in the west. High-value areas of EPs were primarily distributed in the Hehuang Valley—where farmland is abundant, populations are dense, and urban development is concentrated—and in the Three-River-Source, Pan-Gonghe Basin, and Qilian Mountains—where water resources are plentiful and vegetation coverage is high. In contrast, low-value areas were mainly found in the Qaidam Basin, which features a vast area, sparse population, and predominantly arid desert landscapes. (2) The supply-demand indices for FP, WC, and OR displayed upward trends, whereas those for CS and SR showed downward trends. Areas where FP and WC supply exceeded demand tended to contract, while areas experiencing shortages of CS and OR expanded, with most of these shortage areas located in Hehuang Valley. (3) FP, WC, and SR were primarily characterized by a spatial matching pattern of “low supply and low demand”, while CS and OR were dominated by a spatial mismatch pattern of “high supply and low demand”. (4) The spatial agglomeration of EPSDI gradually intensified. With the exception of OR, whose supply-demand index was mainly characterized by low-low agglomeration, all other indices were primarily dominated by high-high agglomeration.
