- Abstract:
- In order to provide a scientific basis for regional resources allocation and population policies in the new round of land-use planning revision, the paper aims to explore the scientific method of calculating the population carrying capacity of the method of cultivated land. First, on the basis of intorducing the accounting method of theoretical and realistic production capacity construct the prediction model about future production capacity of cultivated land, forming the calculating method of population carrying capacity which is based on the population projection method of Logistic biological model and population growth equation model in the three consumption levels, well-off, comparatively well-off and surplus. Then, the paper taking Lulong County as an example makes an empirical study, the results show that the production capacity are 256 826.96 and 299 631.45 ton in 2010 and 2020 which can meet the food consumption demand in well-off and comparatively well-off, but can’t meet the food consumption demand in surplus, overloading 22 837 and 56 617 people. The empirical study show that the calculating results adapt to local conditions is a more scientific method of calculating population carrying capacity.
