The area of agricultural Huaihe River basin only accounts for 2.8% of the national total. However, cultivated land and population all account for 12.5% of the national total. The proportion of grain output in the whole country has remained within 12% until the 1970s. After entering the 1980s, the proportion was significant (Up to 15.9% of the national total in 1985 (the annual grain output in the Huaihe River basin accounts for the proportion of the whole country in Table 1). Now the Huaihe River Basin has become China’s major producing areas of wheat (31% of national output), soybean (accounting for 25% of the country), cotton (accounting for 26% of the country) and oilseeds (accounting for 20% of the national total). The per capita arable land in the Huaihe River Basin is 1.6 mu, which is higher than those in the southern areas such as the southern Jiangsu, the Jiaxing-Huzhou Plain and the Pearl River Delta, and
