中文摘要
将试验成功的微区域集水系统技术体系应用于农业山区面源污染控制中,在滇中地区建立永久试验区(包括农业山区耕地对照小区和微区域集水系统试验小区),在应用微区域集水系统技术体系的条件下,以表生面源污染为主要控制对象,以面源污染物的输出途径和输出规律为主要研究目标,通过对地表径流的产生规律、面源污染物的迁移、转化规律以及面源污染控制条件下污染物的迁移转化规律等方面的研究。明确了山区坡耕地为小流域水平上径流和泥沙输出的主要"策源地",是山区农业面源污染产生的"源头",明确了微区域集水系统技术体系对水土流失"策源地"地表径流和泥沙的控制功能和面源污染的"源头"控制功能,初步明确了主要农作物对面源污染物迁移、转化中的作用,提供了微区域集水系统组成部分的空间组合模式和微区域集水系统技术体系的耦合组装模式及其技术规程。在国内学术刊物和学术会议上发表了研究论文26篇、已录用2篇,出版专著(教材)1部,待出版专著(教材)1部。为应用于云南山区控制农业面源污染的微区域集水系统空间格局布设、结构优化、合理规格尺寸的确定和技术体系的耦合组装提供了理论依据。
英文摘要
The Micro-water-harvesting System (MWHS) tested successfully was used in controlling agricultural no-point resource pollution. The permanent test section was built in mid-Yunnan. The controlling object is the surface produce no-point pollution. The output track and rule of no-point pollutant, produce rule of surface runoff, moving and transform rule of no-point pollutant in controlled conduction by MWHS and so on were studied. The research results as following: (1) The slope plowland is the main land type outputting runoff, mud-sand and agri-no-point pollutant in mountain watershed. The MWHS have the functions as controlling surface runoff and mud-sand and preventing no-point pollution occurred in the main soil-water erosion source area. The effect of main crops transfering no-point pollutant was wised preparatorily. The combination model and technic standard of SWHS was educed. The 26 research articles were published in national publication. A textbook was published by the Chinese Forestry Publisheng Company in 2008. Another textbook will be published by the Higher Education Publisheng Company in 2010. These results afforded the theory for the structure arrange, frame optimized and size confirmed of SWHS controlling no-point pollution in Yunnan mountain area.
