1999年怀柔山区持续高温少雨，遇到了比大旱的1997年更为严重的干旱。但令人振奋的是，由于大规模兴建的水利富民工程有效地抵御了旱魔的侵袭，凡是有水利富民工程的农田、果园，依然获得了好收成。更可喜的是，以水利富民为龙头的山区综合开发工程，确立了农民的经营投资主体 In 1999, the Huairou Mountains experienced persistent high temperatures and little rain, and met a more severe drought than the severe drought in 1997. But it is heartening that due to the large-scale construction of water conservancy projects to effectively resist the invasion of the devil, all farms and orchards that have water conservancy projects will still have a good harvest. What’s more gratifying is that the comprehensive development of the mountainous area, led by water conservancy and enrichment of the people, has established the main business investment for farmers.
