1Understanding sustainability of soil and water resources in a critical zone perspective显示文摘Soil and water resources are fundamental for human beings.Understanding the status and the evolution of regional water and soil resources is the prerequisite for their sustainable management.China is severely constrained by water and soil resources which are subject to soil forming processes under different natural factors such as climate and relief,and also influenced by diversified landuse histories and intensities.Quality and security of water and soil resources are therefore influenced by both natural and anthropogenic processes.Ganlin ZHANG Yongguan ZHU Ming'an SHAO 2019Science China Earth Sciences2019,62,11:7
2秸秆还田及配施氮肥对土壤微生物群落结构及铁氧化菌丰度的影响显示文摘选用镇江含铁量较高的水稻田土壤,设置单施氮肥(T1)和秸秆还田配施不同量氮肥(T2、T3、T4、T5)的小区试验,采用16SrDNA高通量测序分析测定水稻成熟期不同处理土壤养分与细菌群落结构及铁氧化菌。结果表明:与单施氮肥相比,秸秆还田及秸秆还田配施不同比例氮肥可提高土壤细菌均匀度,但对细菌丰富度及群落组成无显著影响;在细菌门水平上,各处理土壤中优势菌群中前3位均为变形菌门(Proteobacteria)、绿弯菌门(Chloroflexi)和酸杆菌门(Acidobacteria)。秸秆还田配施氮肥后变形菌门的相对丰度有所增加,而绿弯菌门则呈下降趋势。典型的铁氧化细菌Gallionellacea为变形菌门主要细菌科,其丰度随氮肥配施量的增加而增加,且与土壤三价铁呈正相关、与含水量呈负相关。综上所述,秸秆还田配施氮肥对水稻土微生物的多样性及铁氧化菌丰度具有一定的影响。王娟娟 马云 狄霖 杨艳菊 徐福蕾 钱晓晴 2022扬州大学学报(农业与生命科学版)2022,43,1:5
3Nanozyme-mediated elemental biogeochemical cycling and environmental effects显示文摘In Earth systems,thousands of terragrams(Tg)(1 Tg=10^(12) g)of mineral nanoparticles move around annually.Some mineral nanoparticles have exhibited unexpected intrinsic enzyme-like characteristics(so called“mineral nanozymes”),and are ubiquitously distributed in natural ecosystems such as the atmosphere,oceans,waters,and soils.Compared with natural enzymes,these mineral nanozymes have several advantages such as tunable catalytic efficiency and robustness to harsh conditions,e.g.,heat,acid,and alkaline conditions.As mineral nanozymes are new products of multidisciplinary cross-cutting,they have been widely applied in various fields.This review,for the first time,systematically introduces the species and properties of mineral nanozymes in Earth systems,discusses the critical roles played by nanozymes in environmental biogeochemical cycles,compiles the interfacial processes and mechanisms of mineral nanozymes,and provides an overview of the future prospects of mineral nanozymes.Zhi-Lai CHI Guang-Hui YU 2021Science China Earth Sciences2021,64,7:2
