养分流

温度还会影响分解的速度，从而影响养分流的速度。

Temperature also affects the rate of decomposition and thus the nutrient flux rate .

同一雨强条件下，土壤流失量与养分流失量呈显著的正相关关系。

There was significant positive correlation between the amounts of soil loss and nutrient loss .

土壤养分流失量与雨强及泥沙流失量呈正相关关系。

The amount of lost nutrients were correlated positively with rainfall intensities and lost sediment .

以此为基础，估算了各种利用方式下土壤养分流失量；

After estimating the soil erosion rate of various ways of land uses , the quantity of soil nutrient loss is calculated .

两种液态地膜处理的土壤侵蚀量和养分流失量没有显著差异。

The differences of soil erosion and nutrient losses through runoff between the treatments with two prepared films were not significant . 4 .

生态型经济林复合模式在水土保持以及防止养分流失等方面具有比较好的效果，并且对于不同的类型，泥沙流失与径流之间，泥沙流失和径流分别与降雨量之间呈现出不同的函数模型；

There are different function models between runoff and sediment , between runoff and rainfall , between sediment and rainfall for different ecological restoration models ;

降雨强度与土壤侵蚀量和养分流失量均呈指数函数关系。

The relations of rainfall intensity and the soil erosion amount and that of rainfall intensity and nutrient loss can be both described by exponential functions .

室内模拟降雨试验结果表明，覆盖自制的两种液态地膜后，都能显著减少土壤侵蚀量和养分流失量。

The results of the simulative experiment showed that mulching with the two liquid films prepared could significantly reduce soil erosion and nutrient losses through runoff .

坡耕地土壤侵蚀厚度、侵蚀量及养分流失量均随着坡耕地坡度的增加而变大；

The erosion thickness of sloping land , erosion amount and the loss amount of nutriment are all become big along with the increase of the cultivated land gradient ;

通过对农田养分概算看出，坡耕地的养分流失量占到农田养分总输出量的59.5%～76.2%。

It can be seen from the calculation that the loss of nutrient of sloping farmlands occupies 59 . 5 % - 76 . 2 % of the total nutrient output of farmlands .

林地虽然养分流失量远远小于农田，但是，受林地面积的影响，在制定河流负荷量时，应考虑农田和林地对河流的综合负荷。

Woodland although nutrient loss , but far less farmland , forest area , by the influence of river in formulating should be considered when the load on the farms and woodland river comprehensive load .

在高雨强下，基质的泥沙与养分流失量仍处于较低水平，表明岩石边坡喷播植草护坡工程具有较好的抵抗降雨能力。

The erosion losses of soil and nutrients kept a low level , even under higher rain intensity , which indicated that grass sowing by spraying for rock slope protection had good potential to resist rainfall .

缓释肥料作为一种新型肥料以其明显提高肥料利用效率，降低养分流失量业已成为国内外研究热点之一。

The controlled release fertilizer had become one hotspot for the research in this field as a new type of fertilizer for obviously increasing the efficiency of using fertilizer and decreasing the quantity of the losing nutrition .

探究了雨型和降雨强度对养分流失的影响。相同雨型和下垫面条件下，黑土区坡耕地养分流失量随降雨强度的增大而增加。

The Nutrient losses from sloping farmland increased with rainfall intensity increase under the same rainfall pattern and underlying surface , and nutrient losses had positive correlation with rainfall intensity in same period under various rainfall patterns .

对天然降雨径流携带养分流失过程进行了研究，径流携带养分浓度随产流的进行总体呈下降趋势，最后趋于稳定，不同生态修复措施径流养分流失浓度均远小于裸露对照小区；

Analyzing nutrient concentration removed with runoff process , it had a generally downtrend along with runoff , tending to stable at final phase , and nutrient concentrations removed with runoff on different ecological controls were all lower than bare soil ( CK ) .

本研究从控制养分流失的源头出发，兼顾作物生长及粮食安全，以控释肥对坡耕地氮、磷养分流失及坡耕地小麦、玉米生长的影响为主要研究内容。

This study started from the views of controlling nutrient loss and also paid an attention to food security . The main research content was investigating the effects of controlled release fertilizer on nutrient loss and the growth of wheat and maize on the slope land .
