WASHINGTON (AP) _ More than half of American adults are satisfied with the level of government services and taxes, according to results of a recent poll released by the Advisory Commission on Intergovernmental Relations.

The poll also found that 41 percent of those questioned favored a more powerful federal government - a significant increase from 1982 when 30 percent said they would like to see the government use its powers more vigorously.

The poll of 1,004 randomly selected adults was conducted May 17-25 by the Gallup Organization of Princeton, N.J., and released Wednesday. The margin of error was plus or minus 4 percentage points.

Asked how they felt about the level of government services and taxes, 51 percent said they would ''keep services and taxes about where they are.''

--- Senate Panel Votes for Hike in Park Entrance Fees

WASHINGTON (AP) - The Senate Energy and Natural Resources Committee, endorsing a Reagan administration request that has little support in the House, has voted to more than double national park entrance fees.

Cleared for floor action on Wednesday was legislation that would allow the National Park Service to charge a maximum entrance fee of $7.50 per vehicle, up from the maximum $3 that has been in effect since 1972.

The bill would allow walk-up fees of $3, twice the current level, and raise the cost of the Golden Eagle pass for unlimited annual admissions from $10 to $25.

Under the plan, the Golden Age pass, allowing senior citizens unlimited park access for a year, would be priced at $10. It now is free. Handicapped people would continue to have free entry.

The legislation specified that the money collected through park fees be retained by the National Park Service.

--- EPA Banning Use of Pesticide on Golf Courses, Sod Farms

WASHINGTON (AP) - The Environmental Protection Agency plans to ban the use of the insecticide diazinon on golf courses and sod farms because it kills too many birds.

The agency said Wednesday it had received reports of 60 incidents in 18 states where diazinon was believed to have been responsible for killing 23 species of birds. Twenty of these incidents were on golf courses and 20 on other grassy areas such as parks.

The Agriculture Department opposed a ban as premature and said alternative measures had not been adequately considered, but EPA's Scientific Advisory Panel for pesticides supported the ban.

The EPA said it expected that the nation's golf courses will have to spend $937,000 more each year in switching to other pesticides while sod farms would have to spend $300,000 more.

--- Workers With AIDS OK, Says Health Secretary

WASHINGTON (AP) - The secretary of health and human services says restaurant owners should allow employees with AIDS to continue working in their kitchens if that is all that's wrong with them.

A waiter or kitchen worker with AIDS should only be taken off the job if there is ''evidence of other infection or illness for which any food service worker should also be restricted,'' Dr. Otis R. Bowen told members of the National Restaurant Association on Wednesday.

''All the epidemiologic and laboratory evidence we have indicates that blood-borne and sexually-transmitted infections like AIDS are not transmitted during the preparation or serving of food or beverages,'' Bowen said.

''No instances of this happening with AIDS have been documented.''

--- U.S. Ready to Accept Cuban Political Prisoners

WASHINGTON (AP) - U.S. officials have told Cuban President Fidel Castro that the United States is ready to accept long-term political prisoners held in Cuban jails, says a ranking State Department official.

But the official, Elliott Abrams, assistant secretary of state for Latin American affairs, said Castro ''has never agreed to let them out.''

Testifying on Wednesday before a House Foreign Affairs subcommittee on human rights, Abrams acknowleged that the United States as a matter of policy is not admitting some Cuban prisoners who were jailed more recently.

He said the goal is to put pressure on Cuba to restore the Mariel agreement under which Cuba agreed to accept the return of Cubans with criminal records and to permit the immigration of political prisoners and ordinary Cuban citizens who wish to leave.

Cuba scrapped the agreement after Radio Marti, a federal government radio station, began broadcasts to Cuba in Spanish in May 1985.

--- Asian Gangs Growing in U.S., Officials Say

WASHINGTON (AP) - Asian gangs are growing stronger in the United States, boosted by a wave of immigration from Hong Kong, say law enforcement officers.

So far, the gangs tend to restrict their violence and extortion to their own ethnic communities in the United States, but their thefts, prostitution and drug trafficking involve the general population, witnesses testified Wednesday before the Senate Permanent Subcommittee on Investigations.

Cynthia Christfield, staff counsel to the subcommittee, said the staff's own investigation turned up emerging criminal groups in the United States from other points, including Vietnam, Japan, Korea and Taiwan.

The Chinese underworld in the United States also has links to Taiwan, and increasingly Chinese who are linked to the gangs are coming into the United States through such Latin American countries as Guatemala and El Salvador, said John McKenna, supervisor of the San Francisco Police Department's Asian Gang Task Force.
