Abstract: The impact of land use on the agrolandscape at the village level between Baka and Daka, Xishuangbanna, Yunnan was explored. The results show that the intensity index of human disturbance ( HD ) is 3.196 5 in Baka, higher than that of Daka because of lack of a large area of natural forest of commonweal. Correspondingly, the fragmentation index of grain and cash crops landscapes of Baka ( R i 0.069 2 and 0.098 0 hm ^-2 ) is higher than that of Daka, respectively. On the other hand, the heterogeneity, evenness and dominance indexes of the landscape of Daka ( H 1.459 5, E 0.664 2 and D 0.737 7) are higher than those of Baka, respectively,due to additional commonweal forest, scenic forest and water in Daka. Hence, Daka can maintain sustainable development depending on the commonweal forest. Cash crop plantations and grain crop farmlands make up a large proportion of the total, indicating that cultivation of grain and cash crops is the key to development of the mountain regions there. However, expansion or maintenance of the acreage of paddy fields contributes greatly to the increase in population carrying capacity of the land. Under the impact of the market and techniques, the scales of the agrolandscapes fluctuate from year to year, but remain stable from a long-term point of view. Nationality cultural policy and market have great impact on land use and landscape patterns of the two villages.
