英儿沟流域是偏关县桑林坡流域的一条支沟,总面积3km~2,治理总面积3.3km~2(包括分水岭外的部分梁峁地)。该流域包括城关、天峰坪2个乡镇的4个村,有3040口人,1140个劳力,人口密度150人/km~2。该流域由8道梁峁、18条沟组成,沟壑密度3km/km~2。水土流失面积4950亩(包括分水岭外部分面积在内),土壤侵蚀模数10400t/km~2。该流域地形破碎,沟深坡陡,沟道狭窄,土质沙松,植被少,覆盖低,水土流失严重。流域平均海拔1200米,最高气温38.1℃,最低气温-31℃,年平均降雨量440毫米,无霜期130~145天,年平均风速2.1米/秒。由于自然环境恶劣,农业生产水平低,亩产徘徊在50公斤左右。
Yingergou watershed is a tributary of Sanglinpo watershed in Pokuan County, with a total area of 3km ~ 2 and a total area of 3.3km ~ 2 (including part of the Beiluo area outside the watershed). The basin consists of 4 villages in Chengguan and Tianfengping 2 towns and 3,040 people with 1140 labors and a population density of 150 persons / km ~ 2. The catchment consists of 8 beams and 18 ditches, with a gully density of 3km / km ~ 2. Soil erosion area of 4950 mu (including watershed part of the area), soil erosion modulus 10400t / km ~ 2. The terrain of the basin is fragmented, with steep dips and narrow channels, sandy soils, few vegetation, low coverage and serious soil erosion. The basin average elevation of 1200 meters, the highest temperature of 38.1 ℃, the lowest temperature of -31 ℃, the average annual rainfall of 440 mm, frost-free period of 130 to 145 days, the average annual wind speed 2.1 m / s. Due to the harsh natural environment and low level of agricultural production, the output per mu hovered around 50 kilograms.
