At the same time, applying analytic hierarchy process (AHP) to determine the index weight, constructing judgment matrix by consulting experts, each index weight of comprehensive evaluation systems of three special types green space can be calculated by using the sum-product method of AHP. Consequently, the comprehensive evaluation systems of three special types green space can be established and applied in the three green space in Shanghai.
1. The index systems of three special types green space which respectively attached to hospital, precision instrument factory and residential area don't show much difference. Each of them includes three levels: the goal layer(A),the criterion layer(B), the index layer(C).
