围垦

To enlarge finite land, also give to littoral land enclose tideland for cultivation coequal take seriously.

为了扩大有限的陆地，对于海滨土地围垦也予以同等重视。

Because they do disafforestation, opening up grasslands, reclaiming field from the intertidal zone, finally cause seriously ecology losing balance and destroying, forest decrement, soil erosion serious, climate worsing, desert broadening the scope, drought and flood harm frequently appearing, all these makes whole ecology going to worse and ...

因毁林开荒、开垦草原、围垦滩涂，结果导致生态平衡失调和破坏，造成森林减少、水土流失严重、气候恶化、沙漠化扩大，洪旱灾害频发，使整个生态环境趋于恶化，最终影响到人类自身的生存。本文列举了巴州地区土地开发的现状，分析了土地开发对生态环境造成的影响，并提出了生态环境保护对策与建议。

At the present,eco-environment in the wetland of the downstream of Yellow River is deteriorated with the agricultural and industrial water diversion,sewage drainage,farmland reclamation,water and soil erosion,immoderacy hunting and fishing.

当前，因工农业采水、排污、围垦、破坏水土、引黄淤地、过度狩猎和捕鱼等造成黄河下游湿地生态环境趋于恶化。

The structure of ecosystem could be summarized as natural mudflat and artificially reclaimed area.

围垦是滩涂生态系统变化的重要驱动力，围垦通过土地利用和土地覆被改变滩涂生态系统结构和功能。

Reclamation of tidal flat is one of the main ways to get a dynamic balance of the total amount of plowland. With the development of social economy and the increasing demand for plowland, the contradiction between tidal flat reclamation and environment protection becomes more and more outstanding.

滩涂围垦是基础设施建设占用大量耕地情况下江苏省实现耕地总量动态平衡的主要途径之一，随着社会经济的发展和对土地需求量的不断增加，滩涂围垦与海岸带环境保护之间的矛盾日渐突出。

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.

浙江大学硕士毕业论文浙北海涂土壤水分特性及溶质运移模拟研究 4、海涂土壤的导水能力强，且土壤剖面备土层的饱和导水率变化大，原状土的饱和导水率远大于扰动土的饱和导水率，围垦时间较早的海涂土壤的饱和导水率较围垦时间晚的海涂土壤的饱和导水率要小；不同含水量下的非饱和导水率变化范围很大，最大值与最小值差距可达 10'③ 5、容重的不同对入渗率、扩散率、非饱和导水率都有影响，容重小，入渗率、扩散率、非饱和导水率也花 6、在海涂土壤中运移的氯离子是一&惰性离子&，氯离子在土壤运移过程中的分布有一定的确定性和重现性，与入渗时间和入渗速度无关，溶质运移过程中，入渗溶液的浓度和海涂土壤的质地对溶质运移综合扩散系数DSh无明显影响，而土壤容重对溶质运移综合扩散系数DSh有影响，容重小，DSh大。
