为了合理利用黑土,维持黑土的可持续性,有必要对农田黑土的质量现状进行评价。因此,综述了20世纪80年代至今农田黑土的质量指标的研究状况,包括土壤的物理指标、化学指标和生物学指标,其中农田黑土物理指标和化学指标研究较早,研究方法已趋于成熟,而生物学指标(包括微生物、酶,土壤动物)研究起步较晚,但生物学指标能较迅速地评价不同农业过程的土壤质量,对土地利用的变化较为灵敏,但到目前为止农田黑土质量评价体系中还没有利用生物学指标的统一标准。在农田黑土质量指标的研究中除了要结合生物指标外,还需要利用现代分析技术快速灵敏的检测土壤质量,这才能为农田黑土的质量检测及合理开发提供基础数据。
It is necessary to evaluate the soil quality status of black farmland in order to use it rationally and maintain its sustainability. So the author summarized researches on soil quality indication of black farmland from the 1980s, including physical indicators, chemical indicators and biological indicators. Soil physical indicators and chemical indicators of black farmland started to research earlier, and now they has become much mature. On the other hand, the research on biological indicators (including microorganisms, enzymes, soil animals) appeared relatively late. However, it' s worth mentioning that the soil biological indicators could be more rapid to evaluate the soil quality of different agriculture processes and he more sensitive to land utilization. Nevertheless, up until now, the validation including soil biological indicators as a universal soil quality criterion has still been under discussion. In the future, people should integrate not only biological indicators, but also modem analysis technology to detect soil quality so as to provide the basic data for soil quality testing and rational development of black farmland.
