中文摘要 | 土壤侵蚀监测为土壤侵蚀评价和科学研究提供定量表达的手段,为水土流失防治规划、措施设计、效益评价和监督执法提供指导。土壤侵蚀监测经历1个多世纪的发展,监测方法由传统的径流小区观测到现代多学科交叉结合的技术,监测结果也由定性提升到半定量和定量。现代土壤侵蚀监测技术提升了土壤侵蚀监测为科学研究和实践服务的能力:基于土壤侵蚀地形演变的现代地形测量提供各种时空尺度高精度的监测数据;核素示踪成本较低、操作简单,能提供多年土壤侵蚀平均值;沉积泥沙反演根据侵蚀泥沙的沉积特性反推流域土壤侵蚀,成为回溯流域土壤侵蚀历史的有用手段;现代原位监测是基于传感器和无线数据传输等现代技术的土壤侵蚀监测新理念,是满足土壤侵蚀监测快速化、自动化和系统化发展的重要方向。通过介绍土壤侵蚀监测领域出现的新方法和新技术,以期促进其推广和应用。 |
英文摘要 | So il erosion mon ito ring cou ld g ive quantitative expression on soil erosion assessment and research, as w ell as gu idance on soil and w ater conservation plann ing and designing, benefits eva luation, adm inistrative superv ision and judgm en.t The deve lopment o f so il erosionmon itoring has experienced over one century, the techn ique evolved from traditiona l runoff p lo t observat ion to contemporary mu lt-i disc ipline method, and the output resu lts w ere expressed from qua litat ive descript ion to sem -i quantitative and quant itat ive data. Modern erosion monitoring techn iques cou ld enhance the ab ility o f soil erosion monitoring serving for scientific researches and practices: based on landform evolvement caused by soil loss, modern topographic survey could provide h igh accurate erosion in format ion in various spatia l and temporal scales; rad ionuc lide tracing has the advantage o f cos-t efficient and being easy in practice, and annua lmean so il erosion veloc ity can be ca lculated; deposited sediment conversion means that soil erosion in w atershed cou ld be assessed from the properties of deposited sed iments in ponds or lakes, and could prov ide usefu lm eans for co llect ing so il erosion histo ry inform ation; based on modern techniques, such as sensor and remote data transm itting, contemporary in-situ observation is a new idea fo rmon itoring erosion and is an impo rtant outlet of mon ito ring technique developmen,t meeting the need o f being time ly, au tomated and system atic. N ew soil erosionmon itoring methods and techn iques are rev iew ed w ith the a im that they be put into w ide realization and applicat ion. |
