Effective eco-environment rehabilitation is an essential policy issue in arid oasis ecosystem. Since 2007, a policy which focuses on environment restoration and protection was implemented in the Shiyang River Basin of Gansu Province, China. Using Minqin oasis as a case, the effectiveness of policy impacts based on farmers’ perception was evaluated. In addition, an ordinal logistic regression model was used to explore the potential factors affecting farmers’ perception of policy effectiveness. Data were collected from household heads or spouses and other adults (age>18) separately in a random sample of 425 households. The results showed that positive outcomes were achieved, however, two policy measures—the water restrictions and the ecological migration project—were rated at a low level of satisfaction by the farmers. Moreover, 11 determinants were extracted by the logistic regression method, and indicating that economic factors including the ownership of the arable land and the availability of household income turned out to be the most significant. The results can help to establish eco-environmental restoration targets, encourage investments, and lead to the development of more applicable methods for assessing policy effects from the perspective of smallholders in ecologically fragile areas all over the world.

Arbuscular mycorrhizal fungi (AMF) colonize land plants in almost every ecosystem, even in extreme conditions, such as saline soils. In the present work, we report the mycorrhizal capacity of rhizosphere soils collected in the dry desert region of the Minqin Oasis, located in the northwest of China (Gansu province), which is characterized by several halophytes. Lycium spp. and Peganum nigellastrum were used as trap plants in a greenhouse experiment to identify autochthonous AMF associated with the halophytes’ rhizospheres. Morphological observations showed the typical AMF structures inside roots. Twenty-six molecularly distinct AMF taxa were recovered from soil and root DNA. The taxonomical diversity mirrors the several AMF adapted to extreme environmental conditions, such as the saline soil of central China. Knowledge of the AMF associated with halophytes may contribute to select specific fungal isolates to set up agriculture strategies for protecting non-halophyte crop plants in saline soils.
