河北省黄土丘陵区农地土壤风蚀防治技术研究

Research on Control Technology of Farmlands' Wind Erosion in Loess Hilly-gully Area of Hebei Province

风沙是河北省黄土丘陵区较常见的灾害性天气现象之一,多发生于冬春季节。河北省黄土丘陵区近几年的沙尘天气频繁发生给当地及京津冀地区人民的生产、生活和社会发展造成了巨大影响。据有关资料,北京沙尘暴的80%来源于张家口的黄土丘陵区。为了改善这一地区的生态现状,在对黄土丘陵区农地土壤风蚀进行5种不同下垫面条件下试验观测的基础上,通过对试验结果的分析,对丘陵区农地土壤风蚀的影响因素进行了的研究,提出了河北省黄土丘陵区农地防治土壤风蚀的技术措施。

Wind erosion is one of the most calamity weather phenomenon in loess hilly-gully area of Hebei Province, it often occurs in winter or spring. Recently, sand-dust phenomenon happened frequently in hilly-gully area, which produced enormous effect on the production and development of the people in Beijing, Hebei and Tianjin area. According to the relational information, eighty percent sandstorm of Bejing comes from Zhangjiakou hilly-gully area. In order to improve the environment, through the analysis of test observation data, which were based on five different underlying surfaces in hilly-gully area, we studied the influenced factors, then put forward the control technology measures of soil wind erosion of farmlands in loess hilly-gully area of Hebei Province.
