Ecological Landscape

For the research on hill and gully landscape of Loess Plateau, to prevent water loss and soil erosion and improve the ecological environment, the paper analyzes the construction of ecological landscape from the large range to small, puts focus on small watershed and hilly gully, and chooses Baiyun mountain demonstrate area as a case to present its landscape planning and design. The research and its related activities integrated and coordinated multidisciplinaries, like the hydraulic engineering, civil engineering and other disciplines. The project constructed dams, transferred and stored water in the gully which has better conditions, achieved good results. Due to the characteristics of hill and gully regions of Loess Plateau, its ecological environment construction must be closely combined with other disciplinaries. Moreover, it is better to construct different demonstrate areas to well improve the research on macro ecological environment.

Loess Plateau region has the severest problem of The Water Loss and Soil Erosion, not only in China, but around the world as well. Due to severe situation of soil erosion, the natural environment was badly damaged in this region and the economy was also deeply influenced. This paper analyses the present situation of soil erosion and controlling measure for erosion in Loess Plateau region, and concludes some valuable experience in managing small watershed of Loess Plateau region. Concluding、analyzing、advancing and extending these successful experiences will exert an important and directive significance for the ecological construction and sustainable development in China.

<p>In recent years, the significantly decrease of water and sediment in the Yellow River has attracted wide attention from domestic and foreign scholars. The Loess Plateau is the main source of sediment in the Yellow River, which ecological environment changes caused by large-scale ecological construction measures is considered as one of the main factors affecting the water and sediment changes in the Yellow River. In this study, the Wangmaogou small watershed in Loess Plateau was taken as the study area. On the basis of summing up the process of ecological construction in Wangmaogou watershed, and restoring the topography before ecological construction by topographic map, we set up four scenarios of ecological construction to analyzed the characteristics of sediment connectivity under different ecological construction scenarios and the effects of ecological construction on sediment connectivity, which are before ecological construction, only slope measures are built, only channel measures are constructed, and at the same time slope measures and channel measures are constructed. Under the same ecological construction scenario, the index of sediment connectivity (IC) of the basin shows a decreasing trend from ridge to gully, which mean the connectivity of the sediment at the ridge is less than that at the gully, and the gully are more prone to occur soil erosion than ridge. The distributed of large amount of construction land in the middle and lower reaches at the main gully of Wangmaogou small watershed reduces the connectivity of their surrounding sediment, and the region is prone to occur sediment deposition. Eco-construction measures have decreased significantly the sediment connectivity index (p<0.01) of Wangmaogou small watershed, and reduced the occurrence of soil erosion. Laying ecological measures lessened the possibility of local soil erosion, and increased the resistance of sediment in the transport process. Compared with the situation without ecological control, the mean of D<sub>up</sub> index decreased by 75.27% by laying slope and gully measures, while the mean of D<sub>up</sub> index decreased by only 6.45% by laying gully measures.</p>

Soil erosion always leads to decreasing of land productivity, deposition of channels, lakes and reservoirs, pollution of water quality and so on. In the small watershed management, the soil erosion amount should be definite. The erosion modulus is able to quantitatively characterize the average extent of soil erosion. In practice, it is difficult to ascertain the erosion modulus. Several methods to ascertain erosion modulus are introduced in this article. Taken some small watershed of Yellow River in West Henan region as an example, these methods are testified to be feasible in ascertaining the erosion modulus. In the construction of small watershed dam system projects and planning and design of hydro junctions, methods and thoughts can be provided for the determination of the erosion modulus.

This thesis summarizes the main problems of the developing countryside in southern China. The rural infrastructure backwardness causes its overall look backward, losing its local cultural characteristics. It uses landscape planning to realize the optimization of basic rural construction and the beauty of the environment. It focuses on developing the core landscape -- village cultural square and village ecological corridor, using square and corridor segmentation and reasonable layout of village land to optimize the rural landscape.

Analyzing vulnerability and adaptation to soil and water loss is an important part of the study on the human–environment relationship in the Loess Plateau. It has also provided a new perspective for studying the farmers’ adoption behavior of soil and water conservation technology in the soil erosion area of the Loess Plateau. Based on the Turner vulnerability framework, this paper constructs a household-scale index system of soil and water loss vulnerability in the Loess Plateau and evaluates the soil and water loss vulnerability in the Loess Plateau using the field survey data of the Loess Plateau applied entropy method. Finally, we use the binary logistic model to estimate the impact mechanism of farmers’ soil erosion vulnerability on farmers’ adoption behavior of soil and water conservation technology. The main conclusions are as follows: (1) In the total sample, susceptibility > exposure > adaptability, whereas in the Shaanxi and Gansu subsample, susceptibility > adaptability > exposure. The Ningxia subsample was similar to the total sample. For each index, Ningxia > Gansu > Shaanxi; (2) The exposure and susceptibility of soil and water loss have a positive impact on farmers’ adoption behavior of soil and water conservation technology, and natural capital has a positive impact on farmers’ adoption behavior of soil and water conservation technology. Physical capital has a positive impact on farmers’ adoption behavior of biological measures. Financial capital has a negative impact on farmers’ adoption behavior of biological measures and farming measures. Social capital has a positive impact on farmers’ adoption behavior of engineering measures and biological measures; (3) Overall, the marginal effect of the adoption behavior of farmers’ soil and water conservation techniques, adaptability > susceptibility > exposure. Therefore, it is necessary to strengthen the monitoring of soil and water loss, encourage the government and farmers to respond in time, and reduce the losses caused by soil erosion. Enriching the capital endowment of farmers, breaking through the endowment restriction of farmers’ adoption of soil and water conservation technology.
