Shuitu Baochi Xuebao, 2020 为揭示再生水不同灌溉模式下土壤结构性质及导水性能的差异。通过室内模拟土柱入渗试验，以清水灌溉为对照（CK），研究了再生水持续灌溉（RW）、再生水—清水混合灌溉（RW-2）及再生水—清水交替灌溉（ARW）3种灌溉模式对土壤容重、总孔隙度、团聚体稳定性、入渗率及饱和导水率的影响。结果表明：相比CK，各处理容重呈降低趋势，总孔隙度增加，但差异均不显著；再生水灌溉促进潮土>1 mm粒级团聚体向1 mm粒级水稳性团聚体含量对潮土结构稳定性贡献最大；再生水3种灌溉模式下潮土入渗率分别显著增长80.00%~260 ...

Research on the Feasibility of Using Coagulation-filtration to Treat Living Wastewater for Green Land Irrigation [PDF]
, 2006 通过小型模拟试验,研究采用“混凝过滤”方法处理后的生活污水浇灌园林绿地后,对绿地植物生长及环境安全产生的影响。研究表明:生活污水经混凝过滤去除悬浮物后浇灌绿地,不但补充了水分,还为植物提供了一定的营养成分,使植物生长茂盛。生活污水经过80 cm厚的土壤层净化后,其悬浮物、氨氮、无机磷、有机物(CODCr)的去除率分别为84%、97%、90%、68.7%,下渗水的浊度平均为0.5 NTU,氨氮、磷酸盐、有机物(CODCr)平均浓度分别为0.4 mg.L-1、0.06 mg.L-1、13.7 mg.L-1 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Articular cartilage regeneration remains a significant challenge because of its limited intrinsic healing capacity and the inadequacy of conventional treatments for restoring structural and functional integrity. In this study, a novel injectable composite hydrogel scaffold was designed to mimic the extracellular matrix (ECM) of native ...

, 2016 随着世界经济一体化和区域经济集团化进程的加快,加强东北亚自由贸易合作已势在必行。作为中国东北对外开放窗口的大连,正逐渐成长为东北亚重要国际航运中心、东北亚国际物流中心与区域性金融中心。而在这一进程中,恰逢从山东半岛到辽东半岛的渤海跨海大通道也在论证与启动之际,所以大连应当积极跟进时代潮流,勇于承担国家使命,借重这一渤海蓝色新干线,全力打造东北亚自由贸易先导区。为此,应当透视大连市域提升为东北亚自由贸易先导区的时代背景,论证大连市域提升为东北亚自由贸易先导区的发展历程 ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Shuitu Baochi Xuebao, 2006 通过室内土柱模拟试验的方法，研究了再生水灌溉对土壤理化性质的影响。结果表明：再生水灌溉对土壤扩散率和饱和导水率的影响与连续灌溉再生水的次数有关，短时间灌溉有降低的作用，但随着灌溉次数的增加，土壤扩散率和饱和导水率有增加的趋势；同时，随着灌溉次数的增加，土壤pH值降低，土壤有机质和全盐量增加；土壤溶液中各离子浓度有显著变化。灌溉5次之后，除0～10cm土层全盐量为0．107％外，其他各层均低于0．1％的限度；0～10，10～20，30～40cm土层的ESP均在5％～10％范围之内，20 ...

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Journal of Applied Ecology, Volume 62, Issue 8, Page 1889-1901, August 2025.By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...
