摘　　要：选取10个具有代表性的川道地村为研究对象,对种植业用地结构、系统生产力、产值结构、系统稳定性和种植业效益进行了动态分析,结果表明:研究区退耕还林还草效果显著,坡地明显减少,林草地明显增加,种植业用地结构由坡地与川道地为主转变为以川道地为主;种植业结构调整初见成效,由粮食与经济作物为主转变为粮食与蔬菜特别是保护地蔬菜为主的种植结构,蔬菜已成为种植业收入的最主要来源,产值结构趋于平衡,系统稳定性有所提高;种植业产投比较低,种植业已步入高投入、高产出的发展轨道,基本实现了农业增产与农民增收,种植业效益有待提高。The construction of plantation land and production value, system productivity, system stability index, and benefit of crop cultivation were analyzed in 10 representative villages near Yanhe river. Results showed： The effect of returning farmlands to forests and grasses was significant due to the area of sloping farmland reduced and that of forests and grasses increased. The farmland construction of crop cultivation changed from sloping farmland and river - nearby farmland mostly to river - nearby land mainly. Moreover, crop cultivation construction was improved remarkably, such as the construction of crop cultivation was changed from grains and profitable crops mainly to grains and vegetable cultivation mainly, and vegetable cultivation became a main income source The construction of production value turned balanced. System stability was enhanced. However, income vs investment ratio relatively lower, which showed that crop cultivation came into the development mode of obtaining higher income by higher consumption, and yield and income were realized on the whole. But the benefit of crop cultivation needed to improve.
