以“美丽中国”法理念提升草原生态环境法治体系

"美丽中国"作为在宪法中崭新宣示和确立的法理念,凸显生态环境价值的高度性、生态环境建设的系统性、生态环境保护的法治性。草原生态环境是承载"美丽中国"法理念的战略领域和空间。"美丽中国"法理念是指导我国草原生态环境法治保护的重大法理念,要按照"美丽中国"法理念的要求全面提升草原生态环境法治体系及其实施,主要是进一步提高草原生态环境法治的战略定位;完善草原产权制度、草原产业制度、草原公共设施和产品投入建设制度、草原生态环境保护制度、草原经济社会发展和社会保障制度、草原生态环境违法犯罪法律责任制度等;提高草原生态环境行政执法的到位性和执法力度;加强和完善草原生态环境司法保护。     

Mechanical properties of wood materials using near-infrared spectroscopy based on correlation local embedding and partial least-squares

This study used near-infrared(NIR)spectroscopy to predict mechanical properties of wood.NIR spectra were collected in wavelengths 900–1700 nm,and spectra averaged by radial and tangential surface spectra were used to establish a partial least square(PLS)model based on correlation local embedding(CLE).Mongolian oak(Quercus mongolica Fisch.ex Ledeb.)was used to test the eff ectiveness of the model.The cross-validation method was used to verify the robustness of the CLE–PLS model.Ninety samples were tested as the calibration set and forty-fi ve as the validation set.The results show that the prediction coeffi cient of determination(R2 p)is 0.80 for MOR,and 0.78 for MOE.The ratio of performance to deviation is 2.23 for MOR and 2.15 for MOE.

气候变化对通辽草甸草原草本植物物候期的影响

植物物候期的变化直接反映气候变化,并成为全球变化研究的重点。基于通辽市巴雅尔吐胡硕牧业气象试验站1981-2016年主要植物羊草(Leymus chinensis)、冰草(Agropyron cristatum)、委陵菜(Potentilla chinensis)、车前(Plantago asiatica)物候观测数据和同期气象观测数据,研究了气候变化对草本植物返青期、黄枯期和生长季的影响,结果表明:1)研究区近36年来年均气温上升0.35℃·10 a-1(P0.01),年均降水量减少22.73 mm·10 a-1,气候暖干化特征明显。2)草本植物返青期呈一致性延迟趋势,平均每10年延迟1.16~7.60 d。羊草、车前返青推迟主要受2-3月累计降水量减少的影响,冰草、委陵菜返青推迟主要受2-4月、3-4月累计降水量减少的影响。3)草本植物黄枯期变化趋势不同,羊草、冰草黄枯期延迟主要受夏季、初秋累计降水量影响,委陵菜黄枯期提前主要受夏季、初秋的累计降水量和日照时数共同影响,车前草黄枯期延迟主要受夏季、初秋平均气温影响。4)草本植物生长季长度主要受气温和降水量影响。气候变暖后,研究区夏季、生长季平均气温显著上升,降水量逐渐减少,导致羊草、冰草、委陵菜生长季缩短;而车前对气温反应比较敏感,气温升高有利于车前生长季延长。

Analysis on Function Orientation and Development Countermeasures of New Agricultural Business Entities

Along with the rapid advance of industrialization and urbanization process, fostering new agricultural business entities become inevitable for agricultural transformation and the construction of agricultural modernization in China. The status of the new agricultural business entities determines the level of modern agricultural development. In recent years, new agricultural business entities have grew rapidly. However, there are still many problems including the difficulties in financing loans, inadequate agricultural insurance system, bad implementation of agricultural subsidies, jagged agricultural talents and so on. In order to foster new agricultural business entities, countermeasures should be carried out to ensure financial support, perfect the agricultural insurance, strengthen the level of agricultural subsidies, strive to develop the degree of specialization agricultural operators and so on.     

液态有机肥与氮肥配施对棉花生理特性及产量的影响

为优化新疆北疆地区滴灌棉花施肥技术，于2016 年进行了氮肥、液态有机肥配施田间试验。采用单因子随机区组试验设计，共设置3 个施氮水平及对照处理。测定了叶面积指数、叶绿素含量、光合参数、可溶性蛋白含量、产量及产量构成因素。结果表明：氮肥减量20%并配施液态有机肥时，叶面积指数、叶绿素含量、净光合速率、棉花的生理特性及产量均表现最优，其产量比单施氮肥的处理增产48.25%，比氮肥未减量或减量40%且配施液态肥处理的平均产量提高16.61%。施用液态有机肥能有效改善植株的生长状况，提高群体叶面积指数，增加叶绿素含量，增强光合特性，从而促进棉花增产。     

Analysis of the Construction Concept of the 12th Nanning Garden Expo
