This experiment was carried out to examine double cropping system using Italian ryegrass (IRG) 'Kowinearly', whole crop rice 'Yeongwoo' and barnyard millet 'Jeju native' during the Oct. 2020 to Oct. 2022. Three kinds of forage crops were cultivated at paddy field in Livestock Institute, Jeollanamdo Agricultural Research and Extension Services, Jeollanamdo, South Korea. Whole crop rice (WCR) was sown in late May and barnyard millet (BM) sown early June each year after harvesting IRG. We examined dry matter yield and feed value of forage crops depending on harvest time of forage crops during the experimental period. The plant height in heading stage of IRG ranged from 108 to 112cm and dry matter yield ranged from 6,783 to 11,530 kg ha-1. The crude protein (CP) of IRG ranged from 6.0 to 8.44%, acid detergent fiber (ADF) ranged from 55.6 to 60.2% and neutral detergent fiber (NDF) ranged from 32.58 to 36.7%, The dry matter yield of WCR increased as the harvest stage was delayed (14,310 kg ha-1 in milk, 16,167 kg ha-1 in yellow ripen, and 18,891 kg ha-1 in mature). Similar to results of dry matter yield of WCR, dry matter yield of BM increased as the harvest stage was delayed (11,194 kg ha-1 in late heading. and 14,308 kg ha-1 in mature), However nutrient content of WCR and BM showed a decreasing trend. As shown in above results, the productivity of WCR after harvesting IRG was shown to be high at paddy field in the southern region. However, BM also was appeared to have potential as summer forage crops.

Chinese land system has gone through several changes since modern times. Although some transformations are only tentative explorations, they have strong practical significance. During the period from 1851 to 1949, it included the National Land System, Sun Yat-sen’s idea of “equal land rights”, Jinggangshan Land Law and Xingguo Land Law during the Agrarian Revolution, as well as Outline of Chinese Land Law during the Liberation War. The changes of the land system has a distinct characteristics, productivity and production relations decide the change of land system in modern China, and the shackles of feudal ideas hindering such changes, moreover spontaneity and compulsory unification has carried out on the basis of the change of land system, while the cause of revolution in modern China emerging from such transformations.Review since modern times of China tell us the history of the land system change, we will improve the system of land laws and regulations, adhere to protect farmers’ interests, strengthen the position of public ownership is not moved, build a new era of agricultural management system can guarantee the healthy and orderly development of China’s land system, thus to promote the rural revitalization of the foundation and guarantee.

이 연구에서는 현행 복구비 산출체계의 문제점 및 원인을 도출하기 위해 이해관계자를 대상으로 설문조사를 실시하였다. 그 결과, 회신된 181건의 설문지 중에서 75%가 공무원 집단, 25%가 비공무원 집단으로 분류되었다. 업무수행 경력의 경우 공무원 집단에서는 1~3년(39%)이, 비공무원 집단에서는 10년 이상(73%)이 가장 높은 점유율을 차지하여 상이하게 나타났으나, 현행 복구비 산출체계에 대한 이해도는 두 집단 모두 동일한 수준으로 분석되었다. 두 표본집단을 대상으로 복구비 산출체계의 토지이용 유형(산지전용(일시사용)허가⋅신고지(광물채굴지 제외), 토석채취(매각) 지 및 광물채굴지) 및 산지경사 등급(10° 미만, 10~20°, 20~30°, 30° 이상) 분류에 관한 인식을 파악한 결과, 공무원 집단은 비교적 적절하다는 의견을 나타낸 반면 비공무원 집단은 보통 수준 이하의 의견을 나타내 현행 토지이용 유형 및 산지경사 등급을 목적사업 이후의 개변된 산지상황에 부합되도록 보다 세분화할 필요가 있을 것으로 사료된다. 이러한 분류에 따르는 현행 1㎡당 복구비 산정기준 금액에 대해 두 집단이 적당하다 또는 그 이하로 평가하였으나, 비공무원 집단에서는 특히 토석채취(매각)지 및 광물채굴지의 복구비 산정기준 금액이 과하다는 의견을 표하기도 하였다. 이는 매년 물가상승률에 준하여 추가로 복구비를 예치해야 하는 경제적 부담이 원인으로 작용한 것으로 추정된다. 한편, 복구비 산정을 위한 17가지 기준공종의 적정성에 대해 특히 비공무원 집단의 다수가 의문점을 제기하였는데, 수로공 및 녹화공에 해당하는 떼누구막이 적용빈도가 가장 낮았다. 다만, 적용빈도가 가장 높은 공종인 비탈다듬기는 떼누구막이에 이어 적용빈도가 낮은 공종으로도 선정됐는데, 이는 대집행으로 산지복구가 이루어질 경우에는 토공작업이 선행되는 반면 자력으로 이루어졌을 경우 이미 토공작업이 완료된 시점에서 복구설계가 이루어지기 때문이다. 실제로 시행된 복구공사에서도 토공 또는 사면안정공에 소요되는 비용이 가장 많았으며, 복구설계 승인기준에 적합하지 않게 훼손된 대집행 복구공사지 에서는 오히려 복구비 부족의 원인이 되기도 하였다. 이 연구의 결과는 현행 복구비 산출체계에 관한 제도적 개선의 필요성을 보여준다.

With the concerns of global climate change, the significant changes in rainfall patterns have aggravated the occurrence of pollutants from agricultural uplands. Heavy and intensive rainfalls have rinsed a variety of pollutants off the land, sending them into the neighboring water environments which further causes water pollution problems. Recently, the application of PAM(Polyacrylamide) in agricultural lands has gotten much attention for soil conditioning. Therefore, this study aimed to develop the automatic control system applying the chemical flocculant, liquid PAM in order to flocculate the suspended solids and deposit at the bottom of farmland water channel, so eventually minimize the amount of non-point pollutants discharged into receiving water. The optimum feed rate for liquid PAM was calculated through the experiment in artificial water channel and applied to the control system. As the results of the performance test of the automatic turbid water control system installed in the sloped field, the range of turbidity reduction rate was 25 to 33% with the average turbidity of 292 to 498 NTU in water channel.

This study is aimed comparative analysis for business performance of land-based ezo abalone (Haliotis discus hannai) seed farms by standardizing cost structures by region and farming size. The result of survey on average farming incomes by region showed that farming incomes in Haenam and Jindo regions were much higher than those in other regions. Followed by Wando region, incomes in other regions were analyzed to be relatively lower. It is shown that farming incomes became higher as farm size increased. Farming incomes per unit size which were modified from farming incomes by region were highest in Jindo region, followed by East sea region, Wando and Haenam regions. Incomes in Jeju and Yeosu regions were analyzed to be relatively lower. Results on farming incomes per unit size (m2) showed that both farming incomes and profits became higher as size increased. It implies that a scale effectiveness might exist in case of land-based abalone culture system. Impacts of major factors on farming profits and returns on investment in abalone seed aquaculture are summarized as follow. First, only if the survival rate increased by 10% with improvement of component ratio, variable effects became largest. In variable effects of other factors, a variation in Jindo region was largest and on the other hand, a variation in Yeosu region was shown to be smallest.

The dichotomous-choice contingent valuation method is applied to estimate the landscape value of Jeju Island's stonewall fencing farming land. A distribution-free approach, Turnbull empirical distribution model, is employed to solve negative willingness to pay and truncation problems. The data used are collected from the interviews with tourist about willingness-to-pay at the various donation amount levels of Jeju stonewall's landscape value. The evaluation result is shown that the average amount of willingness to pay for the Jeju stonewall fencing farming land is 3,001 won per meter with standard deviation of 511.0 won/m.

The purpose of this study is to develop the landscape resource assessment system(LRAS) to help evaluate the value of landscape resources(Jeju Island's Stonewall fencing farming land) for the introduction of direct payment system of the landscape preservation objectively and to applicate the model in the fields. Delphi survey on Jeju's stonewall experts shows that the order of priority among value evaluation elements on Jeju's stonewall is its harmony with surroundings(34%), the preservation of its original state(34%) and its density and scale(32%). Evaluation system development of landscape resources(Jeju's stonewall fencing filming land) and field observation survey utilizing it consists of the following five steps. Step 1 includes the first Delphi survey on Jeju's stonewall experts to decide its value evaluation elements and their priority. Step 2 is the second Delphi survey on Jeju's stonewall experts to grade pictures of landscape resources(Jeju's stonewall fencing farming land) on the basis of expert-proposed value evaluation standards. Step 3 consists of analysis work using the result of Delphi survey on experts. Step 4 is to select five grade standard pictures according to each of three grading elements of A, B, C belonging to each of the three standards. Then, it is necessary to make panels including five A-grade pictures, five B-grade pictures and five C-grade pictures according to each of the three elements of density, harmony, and original state preservation. Step 5 consists of field observation survey.
