Other AbstractBadlands are extremely developed due to gully erosion in Yuanmou dry-hot valley of Jinsha River. Grass growth characteristics and soil moisture conditions under different slope positions of gully badlands were surveyed and analyzed. The results showed that,1)under different slope positions of gully badlands, the grass growth showed large differences, especially the upper position was significantly different with middle and lower positions (P<0.01). Both the grass coverage and aboveground biomass changed from low to high following the sequence upper, middle and lower.2)Under the same rainfall conditions, soil moisture contents of different slope positions declined in exponential trend with different rates over time, resulting in different soil water content. The drop-off rates changed from high to low following the order upper, middle and lower, accordingly the soil water content showed the opposite order in the same monitoring period.3)The grass coverage and aboveground biomass were both significantly related with the average soil water content during the monitoring periods, and also the finally monitored soil water content (P<0.01), which indicated that the soil water difference under different slope positions was a key factor determining the grass growth in gully badlands.
