    摘要:

    石漠化环境水土综合整治走向产业化,其技术体系与山地混农林业模式及技术研发耦合。通过对158篇相关文献的统计分析,结果表明:(1)时间序列的文献发表数量呈现峰丛状曲线分布,说明该研究有进一步加强的需要。(2)研究内容主要针对试验监测研究、运用技术研究、理论与机理研究、模式构建、示范推广和效益分析6个方面进行,其中以试验监测为主,监测混农林业对土壤理化性质的改良作用以及对生态效益、经济效益和社会效益的影响。(3)研究区域主要分布在中国的北方地区和南方喀斯特地区,说明水土综合整治与山地混农林业相结合的研究主要在干旱半干旱地区和工程性干旱的喀斯特地区。从理论研究、技术研发、模式构建、试验示范、监测评价5个方面揭示石漠化环境水土综合整治与山地混农林业的前沿理论;最后发现石漠化水土综合整治与山地混农林业耦合的综合性理论研究和重大关键技术研发显得滞后,应该加强“五水”赋存动力转化、地表地下空间水土资源联合调配、坡面水土漏失阻控技术、节水增值产业技术、林—粮—草立体空间优化配置技术等方面的研究,以综合性水土整治技术发展混农林业,实现石漠化地区生态修复并带动区域经济产业的发展。

    Abstract:

    As the industrialization is becoming a trend for soil and water integrated regulation on rocky desertification control, its technology system is coupled with mountainous agroforestry models and techniques. The results from statistically analyzing 158 related literatures were: (1)The literature shows a peak cluster curve by years of publication, which indicates necessity of further studies. (2)The previous researches involved several aspects, including experiment monitoring, applied technology research, theory and mechanism study, model construction, demonstration and benefit analysis. Among these studies, a priority had been given to experimental testing by monitoring the physical and chemical improvement of soil properties under the agroforestry as well as its influence on ecological, economic and social benefits. (3)The researched areas were mainly distributed in northern China and the karst area in southern China. The combining studies on the soil-and -water-integrated treatment and the mountainous agroforestry were mainly conducted in the arid/semi-arid regions and the karst areas with engineering droughts (droughts caused by the special geological conditions in Karst areas). This paper also revealed the frontier theories about agroforestry and the comprehensive soil-and-water governess of rocky desertification from five aspects: theoretical research, technological research and development, model construction, test demonstration, monitoring and evaluation. It is finally concluded that the previous researches lag behind in the areas of comprehensively theoretical study and the significant technology development. Studies on the following areas should be further strengthened: ‘five water’ on storage and dynamic conversion; joint operation of water and soil resources from both surface and underground space; technology research and development in preventing water and soil leakage from slopes; industrial technology for saving water and adding value; optimizing allocation technology research, on forest-crops-grass stereoscopic space; developing agroforestry with technology of integrated regulation on soil and water loss to achieve ecological restoration in rocky desertification regions and boost the development of regional economy.
