第三章 研究内容与研究，昌图县、法库县、新民市、阜新县等都是辽宁省产能高的县区，而辽东大局部县区以及辽西凌源、喀左、绥中等县区产能比拟低下。在所有城市当中盘锦市的实际单产一直最高，，, kg/hm2, kg/hm2。综合产能核算结果，辽宁省的中部平原区由于条件优越，地势平坦、降水丰沛等，其农用地产能较高于其他地区，该地区的城市如：沈阳、鞍山、铁岭等都是辽宁的产粮大市。而，对于辽东山区和辽西地区那么因为自然、交通等各方面条件的限制，其产能较低。

Total grain output in China is not only related to the amount of the farmland, but also has very close relation with the quality of agricultural land. .one of the means for production monitoring of quality and quantity of agricultural land is to make agricultural production accounting. Agricultural production capacity calculation both consider the amount of cultivated land will also consider the quality of cultivated land. China is a country , which has so many people and less of land, the increase in the number of cultivated land space is very limited. Of land in our country, there is a big part of the middle-and-low-yielding fields, the proportion of high yield field also is less, and the quality of agricultural land in China has great potential for ascension, so want to improve agricultural production capacity, mainly to improve the quality of agricultural land. When the accounting study on agricultural production after farmland classification and grading of the continuation of research work, the accounting study on capacity of farmland is built on the basis of farmland classification and grading. Agricultural capacity calculation can make the number of agricultural land is stable or has modest improvement, optimization of regional cultivated land quality, in the improvement of regional agricultural production efficiency, strengthen regional agricultural ecological environment construction, the improvement of yield and quality of agricultural land. Agricultural production
