“…Over the past decades, a large number of hybrid optimization models were proposed in system optimization and energy management (Li et al, 2013;Zhu and Huang, 2013;Xu et al, 2016;Zhou et al, 2016;Carvalho et al, 2018;Du et al, 2018;Li et al, 2018). Classically, a great many models were singleobjective linear programming (LP), which aims to identify the most economic solutions with minimized of the total system cost.…”

In this study, an inexact mixed-integer interval stochastic fractional model (IMSFP) is developed for Shandong’s sustainable power system management under uncertainties. Shandong has a high proportion of fossil-fuel power, which has resulted in significant greenhouse gas emissions. Future is an essential period for energy structure transition. Developed IMSFP can effectively tackle dual objective, system efficiency represented as output/input ratios, as well as uncertainties described as interval values and probability distributions in the constraints and objectives. The results indicate that the clean power transition and capacity expansion scheme are sensitive to different constraint-violation risk levels. Obtained interval solutions can provide flexible strategies for resource allocation and expansion capacities under multiple complexities. An economic single objective model (IMCLP) is also developed, which aims at minimizing the system cost. The comparative results illustrate that the IMSFP model can better characterize the real-world power system problems through optimizing a ratio between clean energy utilization and system cost. Biomass and wind power would be major developed electricity forms in the future, and solar energy has great development potential. In short, the proposed IMSFP model is advantageous in balancing conflicting dual objectives and reflecting complicated interactions among system efficiency, economic cost, system reliability, and constraint-violation scenarios.

“…The release of heavy metals such as Zn, Cr, Cd, Hg, and Pb from soil erosion may also pose a risk for human health [9]. Soil erosion can be affected by some key factors such as climate change, land use, and anthropogenic activities [10][11][12]. The high-intensity rainfall events have important effects on soil erosion [13].…”

Soil and water conservation practices (SWCPs) are widely used to control soil and water loss. Quantifying the effect of SWCPs and climate change on soil and water erosion is important for regional environmental management. In this study, the Soil Conservation Service Curve Number (SCS-CN) and the Modified Universal Soil Loss Equation (MUSLE) were employed to investigate the patterns of surface runoff and soil erosion with different SWCPs in the hilly region on the Loess Plateau of China. The impact of climate change under RCP4.5 and RCP8.5 emission scenarios was considered from 2020 to 2050. Surface runoff grew with the increased rainfall and rainfall erosivity, while soil erosion presented large variations between years due to uneven distribution of rainfall and rainfall erosivity under two scenarios. Different SWCPs significantly reduced surface soil and water loss. Compared with bare slopes, the reduction rates were 15–40% for surface runoff and 35–67% for soil erosion under RCP4.5 and RCP8.5 emission scenarios, respectively. The combination of shrub and horizontal terracing was recommended due to its low water cost for sediment control among seven SWCPs.

“…Excess nitrogen in soil are directly removed by their own tissue absorption (Stottmeister et al, 2003); better more, plant roots release oxygen to soil, which cause aerobic, anoxic, and anaerobic conditions around the rhizosphere (Korol et al, 2016;Weller et al, 2016). Oxygen-rich area is beneficial to facilitate the process of ammonia nitrogen nitrifycation and nitrate nitrogen denitrification, which promotes the conversion and removal of nitrogen (Xu et al, 2016;Zhu et al, 2017). In addition, plant rhizosphere microorganisms are also critical in the absorption of nitrogen (Truu et al, 2015;Yu et al, 2019).…”

Eutrophication is one of major environmental problems in the Lihe area, China. Reducing the entry of external nitrogen is an effective way to alleviate this problem. Plants, growing in ecological embankment can absorb nitrogen from soil and effectively achieve the purpose of reducing external nitrogen into the water. In order to choose suitable buffer zone plants, this paper explores the viability under three nitrogen concentrations (low, middle, and high) in soil of 13 common plants around Lihe area and their nitrogen utilization ability. Results show that there is no obvious relationship between the absorption and utilization of nitrogen and classifications of plants. JNL (Jasminum nudiflorum Lindl.) possesses high plant total nitrogen concentration (PTN), PTN increase ratio, nitrate reductase activity (NRA), chlorophyll content, and excellent chlorophyll fluorescence parameters under the three nitrogen levels, which demonstrates that JNL adapts well in three nitrogen environments and has a high nitrogen absorption capacity. Therefore, it is the first candidate for Lihe ecological embankment. In addition, BML (Buxus megistophylla Levl.), SJL (Sophora japonica Linn.), OJKJ (Ophiopogon japonicus (Linn. f.) Ker-Gawl.), and RPL (Robinia pseudoacacia Linn.) are also promising candidates. This article provides a technical reference for the establishment of Lihe ecological embankment, and the suggested candidate plants include three classifications (arbor, shrub, and herb), which is not only conducive to the local ecosystem stability, but also in line with the landscape design concept.
