Since May 1998, we had made the assorted technique studies on raising the effect of \%Casuarina equisetifolia\% afforestation on the frontal dry sandy land in the draught of C . \%equistifolia \% backbone forest strips on Chihu Forest Farm, Hui\'an County and Chishan Forest Farm, Dongshan County both in Fujian Province.

Since May 1998, we had made the assorted technique studies on raising the effect of \%Casuarina equisetifolia\% afforestation on the frontal dry sandy land in the draught of C . \%equistifolia \% backbone forest strips on Chihu Forest Farm, Hui\'an County and Chishan Forest Farm, Dongshan County both in Fujian Province. Through the experimental studies for about two years, on the basis of analysing the main reasons for the afforestation failure on difficult sites in the draught, the preserving rate of C.equisetifolia afforestation on the sandy land in the draught was raised to 80%~90% by means of selecting the resistant \%C.equisetifolia\% strains for application, determining the afforestation models in line with local conditions and adopting the drought\|resistant afforestation assorted techniques, including digging deeply for site preparation, putting into the earth removed from other places, mixing mud, making the afforestation season earlier, selecting largely rainy days for afforestation, planting deeply with big seedlings, etc., as well as adopting the combinative afforestation methods of ridging tending for preserving the soil moisture and watering for keeping seedlings in the drought season with the dampproof and windproof engineering measures of building sandy dikes and setting up windbreaks. The important breakthrough has been obtained in the respect of afforestation techniques, which provides the useful experience for the national special protective forest strip engineering construction on difficult sites in the draught in coastal zones.

自 1 998年 5月以来 ,在福建省惠安县赤湖林场和东山县赤山林场木麻黄基干林带前沿风口干旱沙地 ,进行提高木麻黄造林效果配套技术研究。经 2年试验研究 ,在分析风口困难立地造林失败主要原因基础上 ,从木麻黄抗逆品系选择应用 ,因地制宜确定造林方式 ,采用深挖整地、放客土、拌泥浆、提早造林季节、选择大雨天冒雨造林、大苗深栽等抗旱造林配套技术以及旱季培土抚育保墒、浇水保苗和筑沙堤设风障防潮防风工程措施相结合的造林方法 ,在造林屡次失败的风口沙地木麻黄造林保存率提高到 80 %~ 90 %。在造林技术上取得了重大突破 ,为海岸带风口困难立地国家特殊保护林带工程建设提供了有益的经验

After making a thorough investigation of the coastal special custody forest stands in Jiangsu province,the conclusion was made that the key problems are disordered management,small green area,low protective effects,and that the countermeasures pointed out are delimiting the extent of the belt,making a comprehensive program,afforesting gradually,enhancing the protective effects and strengthening the protection of forest resource.

对江苏省沿海国家特殊保护林带调查结果进行了分析,指出存在的突出问题是管理混乱、绿化总量小、防护效益低,提出本省沿海国家特殊保护林带建设的具体对策是立即划定界址、加强科学规划、先易后难进行全面绿化、提高防护效益、严格资源保护。

Through the research on the the controlling effects of shelter forest on nonpoint source pollution of agricultural lands in Taihu Lake area,we get some conclusions:The transfer and loss of N and P(main water pollutants) vary with means of rotation,types of crops and the amount of fertilizer.Shelter forest betweens farmlands and ditches can effectively stop and purify such elements as N and P in soil runoffs,thus controlling nonpoint source pollution of agricultural lands.Poplars with the characteristics of...

Through the research on the the controlling effects of shelter forest on nonpoint source pollution of agricultural lands in Taihu Lake area,we get some conclusions:The transfer and loss of N and P(main water pollutants) vary with means of rotation,types of crops and the amount of fertilizer.Shelter forest betweens farmlands and ditches can effectively stop and purify such elements as N and P in soil runoffs,thus controlling nonpoint source pollution of agricultural lands.Poplars with the characteristics of quickgrowing and high value are suitable to be planted as shelterforest in Taihu Lake Watershed.Based on the model of shelter forest,the width ratio of farmland to shelter forest is either between 100∶40 and 150∶40 or between 150∶60 and 200∶60. Such a model can not only save more farm land,but also purify water quality and protect ecological environment.

通过林带对太湖地区农业非点源污染的控制效应研究,结果表明:农田生态系统中N、P等主要水污染物的迁移、淋失状况随轮作方式、作物种类及施肥状况而变化;农田与沟渠间的缓冲林带有利于截留和净化土壤径流中的N、P等物质,从而在一定程度上控制农业非点源污染。杨树生长快、用途广,适于太湖地区营造水环境保护林带。根据缓冲林带模型研究结果,农田与林带宽度比例(100~150)∶40或(150~200)∶60较为合理,这种模型既能少占耕地,又能净化水质、保护生态环境。
