This paper has analysed genesis and development of rill erosion andits control measures on slope land based on simulated rainfall andfield investigation data.It is considered that in the detachmentflow-way of slope surface,as the runoff erovisity is great enough to washsoil lump and to form waterfalls,further the waterfalls evolving intoheadcuts in rill,rill erosion occures and develops.Unconnected rillsare formed by downward erosion of headcuts and runoff washing torill bottom between headcuts,drawing back of the headcuts and collap-sing of the rill wall.Thus the connection of many unconnected rillheadeuts drawing back forms connected rill in a flowway of the detach-ment flow.Meantime,merging and connecting of the rills happenbecause rainfall and runoff erovisity is more or less than soil erosiondurability to change in time and space.The above process not onlyfurther promotes genesis and development of rill,but also creates severerill erosion.It is considered that zero-tillage and remained residue and mulch onthe summer fallow land,level ditch cultivation and strip alternation ofgrass and agricultural crope on the crope land,steep-slope farmlandretired and forest and grass planted are effective control measures ofrill erosion.

在坡面股流的流程上,当径流侵蚀力增大到足以冲刷土块,形成小跌水,进而演化为细沟下切沟头时,细沟侵蚀就开始发生了。下切沟头的下切侵蚀和下切沟头间径流对沟底的冲刷、沟头的溯源侵蚀、沟壁的崩塌形成了断续细沟。而一条股流的流程上多个断续细沟溯源侵蚀的连接,就形成了连续细沟。在这个过程中,由于降雨径流侵蚀力和土壤抗侵蚀力在时空上的强弱对比关系,出现细沟的分叉、合并及连通现象。所有这些过程,不但进一步促进了细沟的发展,而且随之造成严重的细沟侵蚀。夏休闲地的免耕留茬,秸秆覆盖,水平沟种植,草粮带状间作,陡坡地的退耕还林、还草,是防治细沟侵蚀的有效措施。

通过1987、1988两年试验证明:山坡地水平沟种植小麦增产作用显著,亩产比平播增产7%以上,采用机械带肥播种或畜犁开沟施肥溜籽播种,出苗整齐,亩基本苗比平播田多33.3%。水平沟小麦播种时施肥集中,沟垄拦蓄降水,0—40cm土壤含水量高于平播田2.2—0.2%,0—10cm地温高于平播田0.83℃—0.07℃。水平沟小麦春发能力增强,春季亩总茎数高出平播田9.1%,干物质积累量高出平播田60.3%,亩成穗数高出平播田2.6%,穗粒数高出平播1.3个,千粒重增重0.9克。在10°,14°,22.7°三种坡度分别采取三种行距规格播种,小麦亩产量随坡度增大和播种行距的加宽呈正相关。亩施肥N2.5+P1.25公斤,N3.5+P1.75公斤,N4.5+P2.25公斤,施肥量同亩产呈正相关,亩产增长率高达49.75%,其中以亩施N2.5+P1.25公斤产出效益最好,边际产值最高。这种投肥水平,在渭北旱原和黄土高原丘陵沟壑地区具有广泛的推广应用价值。

本文以草灌带状间作、草粮带状间轮作6年试验资料为依据,按水保性能的强弱对不同处理的种植方式进行了分类。利用贝叶斯多类逐步判别法验证了经验分类的准确性。最后用模糊聚类法对不同种植方式的水保效益进行了分析与评价。结果表明:它们水保性能由强到弱的顺序为:柠条→柠条+牧草间作→单种牧草→草粮带状间轮作→粮食作物水平沟种植→普种粮食作物。
