The appropriation of tourism agriculture development in certain region can be judged rationally by the method in which qualitative and quantitative methods are combined; scale and type of regional tourism agriculture development can be confirmed scientifically.The paper chooses 15 different indexes to set up spatial index system of tourism agriculture of Xi'an, according to the overall arrangement request of tourism agriculture and expert's consultation at first; Secondly, the paper divides 200 villages and towns into 6 kinds of different types by the principal component analytic approach and cluster's analytic approach after initial data relevant is disposed. The appropriation and suitable project for the 6 kinds of type are different with each other. Finally, according to relevant zoning principles, on cluster's result, tour-agriculture of Xi'an is divided into "four belts and two districts" in the space.These are tourism agriculture belt along Qingling-Li Mountains, tourism agriculture belt along Wei River, River valley belt, Plain district, Loess estrading district and Qinling-Li mountains agriculture belt.The former four districts among them should be developed especially. The author thinks that tour-agriculture belt along Qingling-Li mountains is the important fruit industry development district of Xi'an in recent years.
There are a lot of artificial fruit forests and hot springs. On existing orchards, wildwood, artificial woods, forest parks and agricultural gardens and animal husbandries should be developed. In tour-agriculture belt along Wei River, the water resource is abundant, and water amusement projects should be developed. The villages and towns in River valley belt is relatively near to the urban district, it is suitable for developing camping, fishing etc there. The Plain district includes two parts: the district to northern Wei river and district around Xi'an city. The tourism agriculture of the district to northern Wei river will be exploited in the future.The district around Xi'an city is the most important area for developing tourism agriculture; different agriculture gardens for plucking, working, educating, and Hi-Tech agriculture showing can be developed there.Qinling-Li Mountains is graceful;the forest reserves here are abundant. Forest tourism and rural tourism can be developed in this belt.
