Agricultural risks in our country have been introduced: firstly, disasters are multiple and frequently happened; secondly, widely affected and seriously suffered. Features of risks also are introduced: the first is the agricultural risk unit is large; the second is the agricultural risk is strongly regional; the third is the agricultural risk is universally half revival. The paper discusses the limits of the agricultural risks management, pointing out that in the management systems of agricultural risks, government finance is strongly burdened, compensations on the catastrophe is small in region, low in level. Based on the above analysis, the protection systems of agricultural risks have been constructed: the first is to establish the reassurance systems of agricultural risks; the second is to establish the risk funds of single agricultural item; the third is to transfer the catastrophe risks through stocks; the fourth is to construct multi leveled countermeasures of agricultural risks.
