Résumé partiel
Taking the desert oasis transitional zone in the middle reaches of Heihe as an example,the characteristics of plant communities and the physical and chemical properties of the soil in the study area were analyzed based on field investigation and laboratory test.The relationship between species diversity and soil physical and chemical properties was analyzed by grey correlation analysis method.The experimental plot is located in the arid area of the northwest.Due to the enclosure policy,there is less human interference,coupled with its special geographical location and climatic conditions.It is used to study the plant community and soil development in the desert-oasis transition zone of the inland river region in the northwest arid area.Ideal place.Compared with other desert-oasis transitional zones,the desert-oasis transitional zone of Linze County has special soil formation process,soil physical and chemical properties,plant community properties,plant species composition,habitat characteristics,spatial structure and dynamic succession,etc.There are obvious differences.The soil has poor water storage capacity,poor soil quality,and low nutrient content,resulting in a simple plant community structure in this area,with very few species,and poor ecological stability.Compared with other research areas,it is more susceptible to damage and disturbance.Therefore,there is an urgent need to study the characteristics of the plant community,the physical and chemical properties of the soil,etc.,so as to provide a scientific basis for the restoration and reconstruction of the vegetation in this area.
