Application of 3S technologies in urban green space ecology

The characteristics of remote sensing applied to urban green space ecology were introduced at first.Then the applications of 3S technologies were discussed,such as investigating urban green space cover,estimating its 3-dimensional vegetable quantity,monitoring its ecological quality,analyzing its spatial pattern and its dynamic change,assessing its suitability,and planning urban green space etc.Some problems were brought forward and the future on applications of 3S technologies were discussed.
