It is great significance to explore spatial allocation pressure grain vegetable production for sustainable utilization resources. In this paper, Province, a typical major grain-producing region base China, was selected case study crop (including grains vegetables). The results will also play an important role demonstration reference management other provinces. three main crops (winter wheat, corn soybean) vegetables with two different planting patterns (protected open field vegetables) firstly were analyzed. Then concept resource quantity quality introduced analyze pattern differences Finally, its influencing factors further explored. showed that:(1) differed greatly, soybean had highest footprint, followed wheat corn. much smaller than that grains, higher protected vegetables. 2019, total 81.1 billion m3, which accounted 78.50%, 21.50%. obviously affected topography, larger northwest southwest Shandong. (2) mean coefficient considering 0.622×104 m3/hm2, 0.416×104 m3/hm2. consistent space, indicated areas high level facing greater pollution pressure. (3) distribution homogeneity whole; resource. Based perspective production, significantly restricted environmental factors, differently economic while social no significant impact scarcity. future, adjustment structure promote coordinated optimization degree resources, optimal This can provide data basis comprehensive understanding production.
