were discussed here in this paper, then the historical outline of red soil loss had been reviewed, soil erosion countermeasures are suggested. The main opinions could be briefly summarized as following. The red soil loss impacts so many aspects of human life, including physical events such as damage to traffic line and farmland, moral events just like deteriorating coast landscape, and biological events for instance of influencing substrate organisum in river and sea. Although the history of soil erosion and conservation could be divided into four ages, i.e. shifting cultivation age before 17 century, Saion age in the middle of 18 century, age of cultivating the mountainous area (Somayama, national forest stands) from 1920 to 1930,and the age from 1950 to present time, it is better to be divided into 6 ages in considering of the proposal of Gaja in 1943. Rapid development of farmland brought up serious soil losses. The physical erosion control countermeasures are being conducted since implementing the SOIL LOSS PROTECTION REGULATION (1994). After implementing the REGULATION, soil erosion control measures are undertaken, and soil losses greatly declined too in the developing project, which was considered as the main factor caused erosion historically. Generally speaking, soil erosion countermeasures include engineering and agricultural measures. As to engineering measures, the following measures could be suggested, such as designing the optional form of farmland plotting on basis of USLE, setting diversion ditch in every tillage plot when arranging the drainage canal and diversion ditch, making the farmland gradient gently, scale of the settling basin and the diversion of fresh and muddy water when choosing the allocation method of soil catch facilities (i.e. settling basin); Within the agricultural measures, mulching and minimum tillage could be considered as effective soil erosion control methods.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3666"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
