| It is well known, our country is a population great nation. Also it is a large agricultural nation, it has above 70% in nearly 1.3 billion populations who are the farmers, and who live in more than 200 million countryside gardens. So our country is a large courtyard nation. With the countryside ecological environment worsening as well as the countryside farming reduced, how using of the countryside garden, changing the farmer life style and how increasing the farmers'income become an extremely important question."Eco-orchard item"constructing is a good answer for this question."Eco-orchard"mode is a eco-agriculture benign recurrent system, which make the agriculture, forest and the breeding as well as microorganism techniques all together. Recently this mode is get more and more popular in the rural area. So its benefits evaluated get an important study domain. However, it is nearly a blank in our country.My study is based on the"five in one"eco-orchard mode in the northwest of china. The main contributions and the conclusions of the research are as following:(1) Based on the conception and the running rule of the"five in one"eco-orchard mode in the northwest of china.Researched the basal principle and the system composing of this mode. Also by studying on the function of the system.We get that this mode has notable benefits.(2) In this research, by using social investigation method, frequency analysis method, varied indicators from literatures have been analyzed. According to the frequency, the background character, major problems and social economic condition of eco-orchard in different regions, those focus indicators has been chosen after analyzing, comparing. Based on this, we inquired specialist and adjusted the indicators. At last, we established a set of indicator system with three levers, which mainly cover economic, ecological and social benefits.(3) According to the indicator system, using AHP fuzzy evaluation method analyzed the comprehensive benefits of the"five in one"eco-orchard mold. Based on Quantity Stat. and grade method, established the judgment matrix, the subjection function and the math evaluation mode.(4) Applying the investigated data from the item-village to the evaluation mode, indicated that the evaluation method and the indicators system are scientific, rational and applied. Therefore, the research offered a convenient evaluation method for workers engaged with the eco-orchard work. |
