Abstract: The stability of ecosystems is studied in cotton field ecosystems controlled by insecticide and by nature. The two kinds of ecosystems are stable ecosystem. But the stability of the cotton field ecosystem controlled by nature is larger than that of the cotton field ecosystems controlled by insecticide. The relation between diversity and stability is analyzed.
