摘要
为了弄清聊城市耕地生产潜力,进一步提高耕地产出率,笔者运用潜力递减法计算聊城市耕地生产潜力,通过分析未来聊城市耕地面积、粮经比和主要作物播种面积,探讨聊城市耕地资源人口承载力问题。研究结果表明:聊城市小麦生产潜力为6911.37kg/hm2、玉米为15445.88kg/hm2;人口承载力在温饱型、小康型、富裕型水平上分别为938.25万人、750.6万人和625.5万人,这表明在富裕型水平上将出现超载。为此,笔者提出了提高聊城市耕地资源人口承载力的途径。
In order to understand the productive latent capacity of cultivated land resource in Liaocheng City,to further enhance the land productivity,productive latent capacity of cultivated land resource in Liaocheng City had been calculated according to the method of potential degression.By analyzing the cultivated land area,the ratios of the grain to economic crops and main crop sown area in future,the author investigated the population supporting capacity of cultivated land in Liaocheng City.The results showed that the wheat productive potential was 6911.37 kg/hm 2 in Liaocheng City,the corn was 15445.88 kg/hm 2.The population supporting capacity in the well-fed type,well-off type and wealthy level respectively was 938.25 ten thousand,750.6 ten thousand and 625.5 ten thousand.This indicated that the level of the well-off would be overloaded.Therefore,the author proposed the way that would enhance the population supporting capacity of cultivated land in Liaocheng City.
