Research and Obstacle Factor Diagnoses of Development Level of State-owned Farms of the Yellow River Basin

Based on the PSR model, the development evaluation index system of state-owned forest farms in the Yellow River Basin is constructed, and the comprehensive development level of state-owned forest farms in the Yellow River Basin is calculated by using the method of entropy weight TOPSIS and secondary weighting. On this basis, the obstacle factor is analyzed by using the obstacle degree model. And the obstacle factor is analyzed by using the obstacle degree model. The research shows that the development level of state-owned forest farms in the basin is not well developed. On the whole, the development trend of the south of the basin is better than the north of the basin, and the lower reaches of the basin are better than the upper reaches of the basin. The main factors hindering the further development of state-owned forest farms in the basin are the investment level of special funds for infrastructure construction, the protection and cultivation level of forest resources and the development level of new forestry industry. There are obvious similarities in the factors affecting the development of state-owned forest farms in different provinces, and similar types of provinces do not show spatial agglomeration and watershed location agglomeration in the geographical sense, which provides a new perspective for the "zoning policy" of state-owned forest farms in various provinces and regions in the watershed.
