With the development of High-resolution Earth Observation system, its application have been made great achievements, especially for the nature resources investigation. But so many sources and application methods of High-resolution Earth Observation applications lead to many problems. How to integrate and clustering the different demands, and how to evaluate the demand satisfaction is the key to the construction of the High-resolution Earth Observation system. The present paper study the requirements modeling and evaluation of nature resources investigation using analytic hierarchy process. The demand of nature resources investigation for VNIR are selected as the focus of this study. Firstly, the common demands of nature resources investigation are extracted and then demand model are established using Demand for four-element model. Secondly, the condensation level algorithm is used to integrate the nature resources investigation demand for the High-resolution Earth Observation. Thirdly, the demand satisfaction of High-resolution Satellite to the nature resources investigation are evaluated using the fuzzy analytic hierarchy process. The results show that the demand satisfaction of demand cluster except R37, R43 and R93 is greater than 8, and the good ratio of demand satisfaction is 88%. The High-resolution Earth Observation system can meet the need of most of the nature resource investigation, but the ability of ecological assessment for the High-resolution Earth Observation system should be enhanced.
