Land use/cover change nearly correlated with global environment change. Tourism development, as an important driving factor of land use/cover, directly influences the land use of tour area. To provide scientific baseline for the optimization of landscape resources, the practices of eco-tourism and sustainable use of land resources, the variational characteristics of land use/cover between 1990 and 2000 in Zhangjiajie National Forest Park were studied, based on the technology of geographic information system (GIS). The results showed that: the park was protected efficiently during the period. From 1990 to 2000, the areas of near mature, mature and over mature forests were almost stable, which are 97.57% for broad_leaved forest, 96.77% for masson pine forest and 77.92% for Chinese fir forest, respectively. The unused land was restored well. The shrubbery was also well protected. 25.38% of the unused land and more than 30% of shrubbery were transferred into broad_leaved forest, masson pine forest or Chinese fir forest, respectively. The young and the middle aged forests were also well preserved. Most of the young and middle aged forests have grown up to middle aged forest and near mature, mature, over mature forests, respectively. The research shows that, on the basis of maintaining the condition of excellent tradition, “the management scheme of Zhangjiajie National Forest Park" should be put into effect continuously. In addition, the result also shows that the phenomena of destroying forests and encroaching farmland still existed. 100% of young forests of masson pines in 2000 was from the middle aged masson pine forest; 74.06% of young aged Chinese fir forests was from near mature, mature and over mature forests of Chinese fir; almost 10% of unused land was from near mature, mature, over mature broad_leaved forest or middle aged broadleaf forest. Additionally, in 2000, 11.19% of residential areas and roads and 34.82% of economic forests were shifted from encroached farmland. Finally, it was proposed that the community should take part in ecological tourism. By doing so, it can improve the living condition of the local residents, strengthen their ecological consciousness, and make them participate in protecting the environment conscientiously. Meanwhile, the resource of cultivated land can be preserved practically by implementing the law of protecting basic farmland.
