Effects of Landscape Positions and Landscape Types on Soil Properties and Chlorophyll Content of Citrus in a Sloping Orchard in the Three Gorges Reservoir Area, China

In recent years, soil degradation and decreasing orchard productivity in the sloping orchards of Three Gorges Reservoir Area China have received considerable attention both inside outside country. More studies pay to effects topography on property changes, but less research is conducted from landscape. Therefore, understanding landscape positions types properties chlorophyll content citrus a great significance this area. Our results showed that had significant effect citrus. The lowest nutrient was detected upper slope position land, while highest exists at footslope terraces. middle significantly higher than footslope. redundancy analysis first two ordination axes together accounted for 81.32% total variation, which could be explained by changes nitrogen, phosphorus, potassium, available organic matter, pH, Overall, study indicates influence Further, provides reference determination targeted land management measures design so quality yield can improved, finally, sustainable development agriculture ecology realized.
