Vegetation accurate configuration method for preventing side slope water and soil loss
The invention relates to a precise vegetation configuration method for preventing and treating slope water and soil loss, which comprises the following steps: collecting undisturbed root-soil complex samples on a natural grassland slope surface and a bare land slope surface, and measuring a relative soil separation rate for representing slope surface erosion characteristics; meanwhile, corresponding soil physicochemical properties are measured and used for representing the soil texture; then measuring the root length density contained in the undisturbed root soil complex; analyzing the relationship between the relative soil separation rate and the root length density, analyzing the influence of the soil texture on the relationship between the relative soil separation rate and the root length density, distinguishing high-texture soil and low-texture soil, and respectively exploring the relationship between the relative separation rate and the root length density of the high-texture soil and the low-texture soil; wherein the corresponding root length density of the high-texture soil is 58.02 km.m <-3 > to 160.00 km.m <-3 >; the corresponding herbal coverage degree is estimated to be 32.02%-51.56%; the root length density of the low-texture soil is greater than or equal to 184.57 km.m <-3 >, and the corresponding herbal coverage is 55.14%; in low-texture soil, 3.3 kg.m <-3 > to 3.5 kg.m <-3 > of straw with the length of 8 to 10 cm is mixed in a soil layer with the thickness of 0 to 10 cm before sowing.
本发明涉及一种防治边坡水土流失的植被精准配置方法，包括在天然草地坡面和裸地坡面采集原状根土复合体样品，测定相对土壤分离速率，用于表征坡面侵蚀特征；同时测定对应土壤理化性质，用于表征土壤质地；然后测定原状根土复合体所含的根长密度；分析相对土壤分离速率与根长密度的关系，解析土壤质地对二者关系的影响，区分出高质地土壤和低质地土壤，分别探究高质地土壤和低质地土壤的相对分离速率与根长密度的关系；其中，高质地土壤对应根长密度为58.02‑160.00km·m‑3；估算对应的草本盖度为32.02％‑51.56％；低质地土壤根长密度≥184.57km·m‑3，对应草本盖度为55.14％；低质地土壤，播种之前在0‑10cm土层掺混长度为8‑10cm的秸秆3.3kg·m‑3‑3.5kg·m‑3。
