采用马尔可夫链分析模型,以山西省吕梁地区为例,对资源利用方式和资源质量的组合状态与作物产量的关系进行了探讨。结果表明:在黄土丘陵沟壑类型区,在少雨情况下,对资源的利用可采取低投入的方式,这样获得的收益反而比高投入合算。在降水正常,尤其是多雨情况下,则应采取高投入的方式。在平原台地类型区,由于无论是少雨或降水正常年份,还是在多雨年份,高投入比低投入获得的产量高得多。
Using Markov chain analysis model and taking Luliang in Shanxi Province as an example, the relationship between the combination of resource utilization patterns and resource quality and crop yield was discussed. The results show that in the gully region of the loess hilly region, under the condition of few rainfall, the utilization of resources can be taken as low input, and the income thus obtained is more cost-effective than high input. In the normal rainfall, especially in rainy conditions, you should take a high investment approach. In plain plains, yields are much higher for high inputs than for lower inputs, either for normal periods of light rain or precipitation, or in wet years.
