耕地数量的锐减是制约我国农业可持续发展的首要非持续性因素。新中国成立以来我国耕地数量已发生三次大滑坡，１９９２年以来我国耕地净减少量的急剧回升预示着我国耕地数量第四次大滑坡的开始。必须采取措施遏止我国耕地锐减的势头。
The sharp decrease of cultivated land is the primary non-sustainability factor that restricts the sustainable development of agriculture in our country. Since the founding of New China, the number of cultivated land in our country has undergone three major landslides. Since 1992, the sharp rebound of the net reduction of cultivated land in our country indicates the start of the fourth major landslide in the cultivated land in our country. Measures must be taken to curb the momentum of a sharp decline in arable land in our country.
