“…However, the above processes varied with slope position and the changes of soil OC and TN by grassland to Korshrinsk peashrub conversion also varied with slope position. The growth of Korshrinsk peashrub is sensitive to soil water conditions (Li et al 2006;Zhang et al 2006) and is largely governed by soil water content. In our study, soil water content at different slope positions followed the order of lower > middle > upper slope (Fig.…”

The effect of conversion of grassland to woodland on organic carbon (OC) and total nitrogen (TN) has significance for global change, land resource use and ecosystem management. However, these effects are always variable. Here, we show results of a study in an arid area in China on profile distribution of OC and TN in soils covered by two different woody tree canopies and outer canopy space (grassland between woody plant canopies). The soils were at various slope positions (upper, middle and lower slopes) for Chinese pine (Pinus tabulaeformis) and Korshrinsk peashrub (Caragana korshinskii) lands, and of different soil orders (Castanozems, Skeletal, Loessial and Aeolian soils). The objectives were to relate the effects of land use change on OC and TN to slope position and soil order. Soil OC and TN were significantly larger at Korshrinsk peashrub slope locations than at Chinese pine slope locations. Soil OC and TN were small at the lower slope position for Korshrinsk peashrub, however, they were largest at the middle slope for Chinese pine. Korshrinsk peashrub always increased soil OC and TN under brush canopy at the three slope positions, while Chinese pine increased them at lower slopes and decreased them at upper slopes. For the soil types, OC and TN in Korshrinsk peashrub land were in the order of Castanozems > Skeletal > Loessial > Aeolian soils. Korshrinsk peashrub also increased OC and TN under brush canopy in the four soils. Our results indicated that soil OC and TN in canopy soils differed greatly from associated values in the outer canopy soils, and the effects of grassland afforestation varied significantly with tree species, slope position, and soil type. Therefore, we suggest that differentiating such factors can be an effective approach for explaining variances in OC and N changes caused by land use conversion.

“…Seedling establishment is often constrained by inadequate precipitation in arid northwestern China (Li et al 2006). Seedling emergence of C. korshinskii increased by 18% when the soil water content in the layer of 0 to 10 cm increased by only 2% (Sun et al 2004).…”

“…Due to scarce precipitation and dry climate, the establishment and growth of C. korshinskii is often impaired by water shortage (Li et al 2006). The film-bottomed planting method, using plastic film as a leak-proofing material under sandy soil, can effectively alleviate soil water stress, keep soil from puddling and packing together, and prevent loss of water and nutrients (Tao andRen 2004, Zhou et al 2007).…”

A field study was conducted to study the effectiveness of film-bottomed treatment (FBT) on the seed germination and seedling establishment of Caragana korshinskii Kom. in the arid Hexi Corridor of northwestern China in 2007 and 2008. The experiment involved three different depths of film-bottomed treatments (DFBT) (80, 90 and 100 cm) and a control with twelve replications in each treatment. Soil moisture, seedling emergence percentage, leaf characteristics, shoot height, main root length, basal diameter, biomass, biomass allocation, as well as root system distribution, were studied and were found to be significantly higher with FBT in respect to the check (CK) values. Soil moisture content increased with depths of film-bottomed treatments. Our study demonstrates that C. korshinskii can be grown successfully using FBT in arid areas and 90 cm DFBT gives the maximum growth-promoting effect.

“…To reiterate, the main challenge is to mitigate rainfall variability in time and in space. We suggest that rainwater collecting and reuse is an effective means to accomplish this and is inline with growing global movement for in situ rainwater harvesting (Andersson et al 2009;Sturm et al 2009;Li et al 2006;Li and Gong 2002). Currently, GIS and RS are most widely used in this area for studying the soil water balance or for determining the location or techniques of rainwater collecting and reuse (Prinz et al 1998;Jain et al 2004;Dashrath 2005;Durga et al 2005).…”

Traditional water allocation at a regional or basin scale can be too coarse to be used in a local area such as a village. For example, in the hilly area of Sichuan Basin the landform is fragmented and land use pattern consists of small farms. Furthermore, seasonal drought occurs frequently due to spatially and temporally variability in rainfall patterns. These droughts often lead to a reduction in crop yield or no yield at all. Due to the remoteness and scale of the farms, the farm populations are dependent on the annual crop yield. A poor harvest can mean serious hardships to the farmers. In order to mitigate the seasonal drought we first analyzed the drought characteristics from both meteorological and soil aspects. The results showed that both the spring droughts and canicular days (dog-day) droughts had in excess of a 60% chance of occurring. Using a water balance approach, we found that a series of storage ponds and bunds could greatly reduce the impact of these droughts.
