Sloping Farmland(坡地)研究综述
Sloping Farmland 坡地 - To improve the stability of sloping farmland, the optimal ratio parameter of composite soil was determined. [1] Sloping farmlands dominate much of Vietnam’s northern borderlands with China. [2] Sloping farmland is prevalent in hilly red soil areas of South China. [3] The characteristics of dissolved organic carbon loss with different fertilization treatments were examined to derive the best nutrient management method for sloping farmland in the Three Gorges Reservoir area where maintaining the soil carbon balance and reducing environmental pollution caused by carbon loss is crucial. [4] Nutrient losses from sloping farmland in karst areas lead to the decline in land productivity and nonpoint source pollution. [5] In addition, this practice can help retain soil moisture and slow down the rainfall runoff rate, particularly on sloping farmland. [6] Assessing how topographic factors (slope gradient, slope length, slope shape, and slope position) and their interactions influence the SOC dynamics in the surface soil of longitudinal ridges of sloping farmland is very important for Mollisols protection in Northeast China. [7] This study reveals that biochar can be used as a potential measure to prevent soil and water loss on sloping farmland in cold regions. [8] Sloping farmland (SpF) is an important component of cultivated land resources. [9] The results implied that the loss of the agricultural labor force and the difficulty of sloping farmlands adapting to mechanized farming were unconducive to farmland utilization efficiency improvement, and the increase in nonagricultural activities in rural areas would increase the difficulty of cultivated land preservation. [10] In-situ observations of soil and water loss on sloping farmland in the red soil region of southern China with a subtropical monsoon environment were taken at 12 runoff plots with four treatments, i. [11] With rainfall, the relative sediment contribution rates from gullies, sloping farmland, grasslands, and branch ditches were 54. [12] Evaluating the impact of the trench farming layout on the loss of nitrogen production and flow of rainfall in sloping farmland can provide a scientific basis for the prediction and effective prevention and control of nitrogen loss in sloping farmland. [13] Relationships of hydrological processes via surface flow (SF) and subsurface flow (SSF) to nitrogen (N) losses from sloping farmlands have been rarely researched. [14] A three-year field experiment was conducted to investigate HR effects on reducing sediment, runoff, and soil nitrogen (N) and phosphorus (P) losses in a sloping farmland. [15] The experimental plot was placed outdoors to simulate the freeze–thaw cycle of sloping farmland under natural conditions. [16] Even in sloping farmlands, soil infiltration via large pores created by roots, wormholes and straw rot continuously increases, and the infiltrating water forms subsurface flow above the plough pan, causing the soil in the cultivated layer to become partially saturated. [17] Water and soil losses from sloping farmlands potentially contribute to water eutrophication and land degradation. [18] Sloping farmland is an important cultivated land resource and erosion source. [19] The changes of soil particle composition and soil fractal dimension were analyzed by taking the 8-year grassland and 31-year grassland in the Yuanzegou watershed of the loess hilly region as the research objects, and taking the sloping farmland as the control. [20] This provided an innovative idea, that is applying the orientation and gradient to the simulation and prediction model of the rainfall erosion process in the sloping farmland in the southern red soil area. [21] To systematically study the soil and water conservation functions of different straw mulching application rates on sloping farmland in karst area of Southwest China, the observation of runoff plots. [22] We analyzed soil water, nutrients, and yields in three different slope sites in the sloping farmland under Yuluxiang pear planted in the loess hilly region of Western Shanxi, across the growth periods and different soil depths. [23] ) is widely planted on China's Loess Plateau, where severe soil erosion mainly occurs on sloping farmlands. [24] Tillage and erosion simultaneously cause soil movement from the top-slope position to the foot-slope position in a sloping farmland, with consequences on variation of soil organic carbon (SOC) content as well as its stability mechanism. [25] Effective soil conservation measures should be taken to weaken the adverse impacts of tillage erosion on POC and AN redistribution in sloping farmlands. [26] Large-scaled activities of the conversion from the sloping farmland to terrace were implemented in the middle 1980s in the studying Luoyugou watershed, remarkably influencing the regime of runoff generation and accordant junction. [27] The objective of this work was to understand the mechanisms of P loss under heavy rain from the purple soil of sloping farmlands. [28] We studied the effect of the conversion of sloping farmland (SF) to woodland (WO), grassland (GR), shrub-land (SH), and terraced fields (TE) on aggregate structure, stability, and stoichiometry in 0–20, 20–40, and 40–60 cm soil layers. [29] We studied infiltration and fractal mechanisms on sloping farmlands in a small watershed in Shandong Province in the rocky mountain areas of northern China. [30] The risk of P loss in topsoil was greater than those of the other soil layers on sloping farmland of purple soil. [31] Sloping farmland is an essential type of the farmland resource in China. [32] The average annual soil erosion modulus of the sloping farmland, mainly distributed at elevations of 1600–2200 m, was estimated to be 2771 t/(km2·a). [33] Rill erosion is one of the most serious problems in sloping farmland of purple soil. [34] Losses of nutrients, water and soil from sloping farmlands have a large potential to contribute to water eutrophication and land degradation. [35] Taking Qingxi small watershed in Hanyuan County of Ya'an City as an example, the effects of four different economic fruit forests on the sloping farmland in the dry-hot valley region on the soil nutrient loss before and after the flood season were studied. [36]为提高坡耕地稳定性，确定了复合土的最佳配比参数。 [1] 倾斜的农田占据了越南与中国北部边境的大部分地区。 [2] 我国南方红壤丘陵区坡耕地普遍存在。 [3] 研究了不同施肥处理溶解有机碳损失的特点，得出了三峡库区坡耕地最佳养分管理方法，维持土壤碳平衡和减少碳损失对环境造成的污染至关重要。 [4] 喀斯特地区坡耕地造成的养分流失导致土地生产力下降和面源污染。 [5] 此外，这种做法可以帮助保持土壤水分并减缓降雨径流速度，特别是在坡地农田上。 [6] 评估地形因素（坡度、坡长、坡形和坡位）及其相互作用如何影响坡耕地纵脊表层土壤的 SOC 动态，对于东北地区的软泥土保护具有重要意义。 [7] 本研究表明，生物炭可作为防止寒区坡耕地水土流失的潜在措施。 [8] 坡耕地（SpF）是耕地资源的重要组成部分。 [9] 结果表明，农业劳动力流失和坡耕地难以适应机械化耕作不利于提高农田利用效率，农村非农活动增加会增加耕地保全难度。 [10] 对亚热带季风环境下的南方红壤区坡耕地水土流失进行了现场观测，在12个径流样地进行了4个处理，i. [11] 降雨时，沟壑、坡耕地、草地和支沟的相对泥沙贡献率为54。 [12] 评价沟耕布局对坡耕地氮素产量损失和降雨流量的影响，可为预测和有效防治坡耕地氮素流失提供科学依据。 [13] 很少研究通过地表流（SF）和地下流（SSF）的水文过程与坡地农田氮（N）损失的关系。 [14] 进行了一项为期三年的田间试验，以研究 HR 对减少坡地农田沉积物、径流和土壤氮 (N) 和磷 (P) 损失的影响。 [15] 试验地块置于室外，模拟自然条件下坡耕地的冻融循环。 [16] 即使在坡地，通过根系、虫洞和秸秆腐烂形成的大孔隙的土壤入渗不断增加，入渗的水在犁盘上方形成地下流动，导致耕层土壤部分饱和。 [17] 坡耕地造成的水土流失可能导致水体富营养化和土地退化。 [18] 坡耕地是重要的耕地资源和侵蚀 来源。 [19] 以黄土丘陵区元泽沟流域8年草地和31年草地为研究对象，以坡耕地为对照，分析了土壤颗粒组成和土壤分形维数的变化。 [20] 这提供了一个创新的思路，将方向和梯度应用到南方红壤区坡耕地降雨侵蚀过程的模拟和预测模型中。 [21] 为系统研究西南岩溶区坡耕地不同秸秆覆盖施用量的水土保持功能，对径流样地进行观测。 [22] 我们分析了晋西黄土丘陵区玉露香梨坡地三个不同坡地的土壤水分、养分和产量，跨越生长期和不同土壤深度。 [23] ）在中国黄土高原广泛种植，严重的水土流失主要发生在坡耕地上。 [24] 耕作和侵蚀同时引起坡地农田土壤从坡顶位置向足坡位置移动，对土壤有机碳（SOC）含量及其稳定性机制产生影响。 [25] 应采取有效的水土保持措施，减弱耕作侵蚀对坡耕地POC和AN再分配的不利影响。 [26] 1980年代中期，在研究的落峪沟流域实施了大规模的坡耕梯田退耕还田活动，显着影响了产流及调合交汇的情况。 [27] 这项工作的目的是了解大雨下坡耕地紫色土壤中磷的流失机制。 [28] 我们研究了坡耕地 (SF) 向林地 (WO)、草地 (GR)、灌丛地 (SH) 和梯田 (TE) 转化对 0-20 年的聚集体结构、稳定性和化学计量的影响， 20-40 和 40-60 厘米土层。 [29] 我们研究了中国北方落基山脉山东省小流域坡耕地的入渗和分形机制。 [30] 紫壤坡耕地表层土壤磷流失风险大于其他土层。 [31] 坡耕地是我国重要的耕地资源类型。 [32] 主要分布在海拔1 600～2 200 m的坡耕地年均土壤侵蚀模数估计为2 771 t/(km2·a)。 [33] 细沟侵蚀是紫壤坡耕地最严重的问题之一。 [34] 坡耕地造成的养分、水和土壤流失极有可能导致水体富营养化和土地退化。 [35] 以雅安市汉源县清溪小流域为例，研究了干热河谷地区坡耕地4种不同经济果林对汛前后土壤养分流失的影响。 [36]
