Use of mangroves by traditional fishermen in Madagascar

Traditional fishing is intensive in Ambaro Bay and around Morondava, respectively on the northwest and western coast of Madagascar. This fishing relies extensively on forest products much of which originates from nearby, readily accessible mangroves. Mangrove wood is used extensively for making the fishing traps and the canoes, for processing the prawn and fish catch, and for domestic use including fencing, housing and fuel for cooking. The increasing scarcity of forest species suggest an over-exploitation as well as a degradation of the ecosystem. A management plan is needed to ensure the long-term survival of the resources.     

Extensive shrimp farming,mangrove clearance and marine fisheries in the southern provinces of Vietnam

Within the last decade shrimp farming in the Mekong Delta of Vietnam has increased by 3500%. Shrimp farming became un-sustainable in the early 1990's due to the un-planned development of this industry and the resulting self pollution of the farms, the destruction of mangrove forest and the outbreak of viral diseases. Historical data on fisheries, fishing effort and mangrove coverage were obtained from the province Minh Hai (lately divided in Ca Mau and Bac Lieu). Analysis of catch and effort data of marine fisheries in the Mekong Delta indicated a severe danger of over-exploitation of fish stocks and further decline can be expected if fisheries management only considers the demand for fish. The relation between the total fish catch (t/year), the mangrove area (ha), the engine capacity (HP) of the fishing fleet and the social incentive for fishing could be described with the model: Total catch=0.449*Mangrove area + 0.614 Engine capacity + 654 Social factor. One hectare of mangrove forest supports a marine catch of 450 kg/year

橡胶树寒害气象等级研究

用我国云南、海南、广东三省主要橡胶种植区内11个气象站建站的2008年11月至次年3月逐日气象资料以及橡胶寒害灾情史料,开展橡胶树寒害等级的研究,为规范橡胶树寒害调查、统计和评估业务提供参考。根据橡胶树寒害的特点,提出橡胶树平流型低温天气过程、辐射型低温天气过程的概念,给出了橡胶树平流型寒害、辐射型寒害和混合型寒害的明确定义,并用极端最低气温、最大降温幅度、寒害持续日数、辐射型积寒、平流型积寒和最长平流寒害过程的持续日数共6个致灾因子,构建寒害指数。依据寒害指数的大小,将橡胶树寒害分为轻度、中度、重度、特重四个等级。同时给出了橡胶树遭受不同寒害等级时可能导致的橡胶干胶减产率和橡胶树受害率的参考值。     

“慢城”理念视角下的闽南传统渔村保护

鲟埔村是福建闽南“三渔女”之一鲟埔女的核心聚集区,是一个独具闽南特色的沿海渔家村落,由于生活变迁,渔家村落逐渐没落。为了对鲟埔村以及其他传统渔村的民俗文化进行系统化保护,文章通过比较分析、实地观察、实证分析等方法,以“慢城”模式在村落物质与非物质层面进行系统化梳理,探索现有传统村落的保护与更新模式,提出一种更适用于鲟埔村保护与更新的模式,使村落精神与文化遗产源远流长,为其他具有特色性、地域性的传统村落提供一定的借鉴意义。     

垂榆冻害调查及其影响因素的分析

对长春市4个不同地点(路段)栽植垂榆的受冻害状况进行了调查与分析,结果表明:4个调查地点垂榆的冻害率分别为67.0%、31.0%、72.0%和92.0%,平均值为65.5%;冻害指数分别为31.0、11.4、49.2和64.9,平均值为39.1。2009~2010年冬春季节持续低温的累积作用是导致发生冻害的主要因素,老龄植株生长后期的嫁接不亲和作用与砧木个体抗寒能力的遗传差异亦是影响因素之一。     

Assessment of ecosystem services as an opportunity for the conservation and management of native forests in Chile

This paper quantifies two important native forest ecosystem services in southern Chile: water supply and recreational fishing opportunities. We analyzed streamflow in relation to forest cover in six watersheds located in the Valdivian Coastal Range (39°50′–40°05′S), the effect of forest management on streamflow in two watersheds in the Valdivian Andes (600–650 m of elevation; 39°37′S), and fish abundance as a function of forest cover in 17 watersheds located in the Coastal Range and the Central Depression (39°50′–42°30′S). We found that the annual direct runoff coefficient (quickflow/precipitation) and total streamflow/precipitation in the dry summer season were positively correlated with native forest cover in the watershed (R² = 0.67 and 0.76; ^*P = 0.045 and 0.027, respectively) during four years of observations. Conversely, a negative correlation was found between summer runoff coefficients (total streamflow/precipitation) and cover of Eucalyptus spp. and Pinusradiata plantations (R² = 0.84; ^*P = 0.010). We estimated a mean increase of 14.1% in total summer streamflow for every 10% increase in native forest cover in the watershed. The analysis of streamflow changes between two paired watersheds dominated by native secondary Nothofagus stands, one thinned with 35% of basal area removal and a control, showed that the former had a 40% increase during summer (four years of observations). The best correlation between fish abundance and forest cover was found between trout abundance (%) and secondary native forest area in 1000 m × 60 m stream buffers (R² = 0.65, ^***P < 0.0001). We estimated a 14.6% increase in trout abundance for every 10% increase of native forest cover in these buffers. Similar approaches to quantify forest ecosystem services could be used elsewhere and provide useful information for policy and decision-making regarding forest conservation and management.
