[目的]揭示皖南地区土壤侵蚀时空分异特征及成因可为该区域的土壤侵蚀防治提供科学依据。[方法]基于RUSLE模型和地理探测器，结合多源遥感数据，探查皖南地区土壤侵蚀时空分布及其影响因素。[结果](1) 2002—2022年该地区土壤侵蚀空间分布差异显著。安庆市北部大别山区、安庆市东南部大别山余脉大龙山片、铜陵市东部与芜湖市中西部狮子山片、池州市与宣城市南部、黄山市内黄山山区和周边齐云山及白际山等地区系主要侵蚀区；而皖江诸市沿江平原及其他诸河河谷平原土壤侵蚀较小。(2) 2002—2022年该地区的土壤侵蚀总体呈“下降—上升—下降”趋势。其中，2002年总侵蚀量为2 231.41万t/a, 2007年降至2 118.05万t/a,而2012年增至2 452.36万t/a,之后持续下降至2022年的2 060.67万t/a。(3)因子探测器的各因子解释力结果显示：土地覆盖类型、坡度、海拔、降雨是该地区的主要影响因素。(4) 2002年、2017年、2022年土地覆盖类型与其他因子共同作用对土壤侵蚀的解释力大于其他因子，而2007年、2012年为植被覆盖度与其他因子共同作用对土壤侵蚀的解释力较为突出。(5)基于2022年的土壤侵蚀数据及因子数据所识别的高风险区域为植被覆盖度63.96°、海拔1 056～1 819 m、年均温度10.46～11.3℃的灌丛。[结论]皖南地区在过去20年中土壤侵蚀状况有所改善，但坡度大、植被覆盖度低、降雨强度高及不合理土地利用的山地丘陵区仍然是高侵蚀风险区域，未来的防治工作应针对这些重点区域。

During the boreal summer,intraseasonal oscillations exhibit significant interannual variations in intensity over two key regions:the central-western equatorial Pacific(5°S-5°N,150°E-150°W)and the subtropical Northwestern Pacific(10°-20°N,130°E-175°W).The former is well-documented and considered to be influenced by the ENSO,while the latter has received comparatively less attention and is likely influenced by the Pacific Meridional Mode(PMM),as suggested by partial correlation analysis *** elucidate the physical processes responsible for the enhanced(weakened)intraseasonal convection over the subtropical northwestern Pacific during warm(cold)PMM years,the authors employed a moisture budget *** findings reveal that during warm PMM years,there is an increase in summer-mean moisture over the subtropical northwestern *** increase interacts with intensified vertical motion perturbations in the region,leading to greater vertical moisture advection in the lower troposphere and consequently resulting in convective *** a process is pivotal in amplifying intraseasonal convection *** observational findings were further verified by model experiments forced by PMM-like sea surface temperature patterns.

Research of Tribological Behaviors of a New Aluminum Bronze

Cobalamin-dependent radical S-adenosyl-L-methionine protein functions with a partner to successively methylate tricyclic indole alkaloid for chuangxinmycin maturation and derivatization

14～(th) Congress of International Federation for Heat Treament and Surface Engineering

作者： xu Jian-lin, wang Zhi-ping, CHEN Chao1. State Key Lab of Gansu New Non-ferrous Metal Materials, Lanzhou University of Science and Technology, Lanzhou, China 2. College of Mechanic-Electronic Engineering, Lanzhou University of Science and Technology, Lanzhou, China

＜正＞ The tribological behaviors were investigated in a new high strength and wear resistant aluminum bronze, with its friction coefficient and wear-rate lower than those of ZQA19-4 and ZQA110-4-4 alloys in terms of Chinese national standard. The results showed that different tribological behaviors were attributed material itself. Under boundary lubrication condition, major wear mechanisms of aluminum bronze are adhesive wear and attrition wear. Its wearability depends mainly on material microstructure, shedding hard-particles, rakes and small pits that can store lubricant. The new aluminum bronze may find wide application in high sliding speed, heavy load and boundary lubrication condition.

Cobalamin(Cbl)-dependent radical S-adenosyl-L-methionine(SAM) proteins constitute the largest collection of the radical SAM superfamily that has hundreds of thousands of individual members. Many of these proteins are involved in the biosynthesis of pharmaceutically important natural products to catalyze chemically demanding reactions. In the biosynthetic pathway of chuangxinmycin(CXM), a unique indole alkaloid antibiotic with potent anti-infective activity, functionalization of the characteristic thiopyrano[4,3,2-cd]indole scaffold by regio-and stereoselective C3-methylation is believed to rely on a Cbl-dependent radical process, which, however, remained to be reconstituted biochemically. We here report the dissection of this enzymatic process, which requires the incorporation of Cxm8, a Cbl-dependent radical SAM protein, with Cxm9, a DUF5825family protein that shares no homology to any proteins of known functions. Cxm8 and Cxm9 function together by forming an unexpected heterodimeric complex that selectively catalyzes C3-methylation of the tricyclic indole-S-hetero ring system in a successive manner, achieving CXM and a recently identified, C3-dimethylated congener. Detailed biochemical characterization,isotope labeling, structural simulation and bioinformatics analysis rationalized the catalysis of the Cxm8/Cxm9 complex and particularly the necessity of the DUF5825 protein for C3-methylase activity. This is the first example that a Cbl-dependent protein acts with a partner to exhibit radical SAM activity.
