The research conducted quantitative analysis on circular agriculture in Jiangsu by estab- lishing assessment index system of circular agriculture development, In 2013, most indices of Jiangsu circular agriculture kept higher than national levels, but many problems exist such as excessive uses of chemical fertilizer, pesticide and mulch. Therefore, it is effective for advancing circular agriculture in Jiangsu to stabilize gov- emment fiscal support and broaden financing channels.展开更多
The effect of three different N-fertilization levels （NI： 625, N2：385 and N3：770 kg hal; where in case of N1 was used the 3-6-10＋3MGO＋30% OM and in cases of N2-N3 the 26-0-0 fertilizers） on fresh and dry weight...The effect of three different N-fertilization levels （NI： 625, N2：385 and N3：770 kg hal; where in case of N1 was used the 3-6-10＋3MGO＋30% OM and in cases of N2-N3 the 26-0-0 fertilizers） on fresh and dry weight of the perennial Rosmarinus officinalis （upright cultivar） was investigated during the 2nd year after establishment at the Experimental Farm of the Technological Educational Institute of Thessaly in Greece （TEI; Larissa plain） in 2015. It is well documented that the crop reaches its potential yield on the third year of cultivation and continues producing biomass for as long as eight years. Complete weather data （air temperature, radiation, air humidity, precipitation） were recorded hourly in an automatic meteorological station, which was installed to the experimental farm of TEI. Upon harvest （November 3rd 2015）, the crop reached a maximum fresh yield of 11.67 tons per hectare and dry yield of 4.3, respectively. The average fresh weight was 8.2, 8.4 and 8.9 t hal and the dry weight were 2.6, 3.1 and 3.2 t ha-1 for the N1, N2 and N3 levels, respectively. Furthermore the higher moisture content was observed in the case of N1 level （68%）. Therefore, the above data show that rosemary cultivation could be a promising alternative crop, especially in case of the consideration that average selling price of dry rosemary in Greece is 3.5 ∈ kg^-1 and the average gross income exceeds the amount of 10,000 ∈ ha^-1.展开更多

Now; after 8 years of project implementation, the ecological recovery effects of the SLCP have become the hot issue of academic circle. This paper; raking the loess hill and gully area of northern Shaanxi as an example, presents a methodology for assessing the vegetation restoration effect of SLCP with normalized difference vegetation index （NDVI）. The key components include calculation of the Growing Season NDVI （GSNDVI）, and estimation of the NVDI change induced by climate and SLCP, respectively. Based on the method, the NDVI change between 2000 and 2006 was obtained using the GSNDVI that excluded the noise from snow and ice. After the part of total NDVI change caused to： climate variation was estimated using empiric formulae, we obtained the part induced by human factors, i.e. the SLCP The human induced part of ND VI change was considered as an approximation indicating the effect of the SLCP on the vegetation. Finally, we analyzed the ND VI change characters of the whole study area, different slope lands and different land use types by spatial statistics method. Results show that the vegetation condition is significantly improved by the SLCP, particularly land types that directly involved in the SLCP, such as steeply slope farmlands, degraded grasslands, etc.展开更多

The measurements were supported by European initiative called CIVITAS Reanissance. The measurements results were used for preparation of documents related to Sustainable Urban Transport Mobility Plan and Noise Action Plan. Traffic congestion is the main source of noise emission in the center Szczecinek. So there was a need to assess the noise emission level. Noise measurements were part of the measure implemented in Szczecinek during the CIVITAS project. It was made during implementation one of the ten measures implemented in Szczecinek. The main objectives of the measure were preparation and acoustic maps of the city center and prognosis the change of traffic noise in the future.展开更多
