结合参与耕地地力评价的实际经验和众多研究成果,综合西南山地丘陵农业区的特点,分析了该项研究实际操作中的难度及原因,探讨了当前该项研究工作的不足,提出以下可持续研究发展方向:首先,可以在参评指标的选择和指标体系建设的过程中,以气候和地势为依据,将研究大区分为几个地力评价亚区,分亚区确定评价指标和权重。水田旱地交错分布区的地力评价工作,尤以西南地区为甚,基于水田旱地实际地块的地力水平及其权重的差异性,建议最好能够分开进行评价。再者,可以注重评价单元赋值的过程中插值方法的选择,可在对采集数据全局认识的基础上,再选择合适的点面赋值方法。此外,在地力评价工作过程中,注意每一细节的完成,因为这些细节的处理结果将直接影响到农业生产和结构化调整。
Based on the actual experience and many research results of the evaluation of cultivated land productivity, the paper analyzes the characteristics and difficulties of the agricultural practice in southwest hilly area and analyzes the difficulties and causes in the actual operation of the study. The deficiencies of the current research work are discussed. The following sustainable research Development direction: First of all, we can divide the research area into several sub-regions for evaluating the sub-regions based on the climate and the terrain in the process of selecting the indicators and the index system, and determine the evaluation indexes and weights in sub-sub-regions. Paddy field dryland staggered distribution of the evaluation of geotechnical performance, especially in Southwest China is even more, based on paddy field actual plots of groundwater level and its weight difference, it is best to be able to separate evaluation. Furthermore, we can pay attention to the choice of interpolation method in the process of evaluation unit assignment, and then select the appropriate point surface assignment method based on the global understanding of the collected data. In addition, attention should be paid to the completion of each detail during the evaluation of geotechnical performance, as the results of these details will directly affect agricultural production and structural adjustment.
