Abstract: The synthetical benefits during the Period from 1988 to 1993 and the potential of grain yield-increasing during the pened from 1995 to 2000 during the agricultural comprehensive development in the Huang-Huai-Hai Plain were analyzed in this paper.Up to 1993.obvious economic,ecological and social benefits were achieved in the region of the agricultural comprehensive development,where 4.09 million hectare middle-low yield land was improved and 0.22 mason bectare wasteland was reclaimed.The annual average growth rate of grain was 4.0 Per cent in the region.The amount of yield-increasing of grain made up 42.5 per cent of the total in the area.The contribution of agricultural development is nearly equal to that of traditional agriculture. According to the forecast,up to 2000.even if the scale of agricultural comprehensive development is the same as that in the preceding six years,it is entirely possible for the amount of yield-increasing of grain to be 9 billion kilogram in the development region in the area.since the water conservancy works are fully used and the scientific and technological contents in agriculture are increased sustainably.
